How to learn to code | Computer Programming




TechLead / Published on Jun 9, 2018
Ex-Google tech lead Patrick Shyu explains how to learn to code quickly and easily, with this one weird trick! 
It's so simple with this 1-step program! Are you looking to hack into the mainframe, bypassing the system security lock to gain root access into the private kernel? 
Well, if I can do it, so can you! * ABOUT SITTING: It is highly unhealthy to sit for long periods of time. 
I always get up and take a short break every 30 minutes. 
Note though that even with breaks, it is known that long periods of general inactivity will put your body to sleep and you need to take longer walks/jogs throughout the day to keep up a healthy metabolism. 
Take care of your back/neck posture as well.

CryptoMining via FPGA



CryptoMining via FPGA's:







FPGA for Dummies & Experts Alike!


The ASICs had overtaking GPU mining, but an alternative to ASIC mining was born. 

The new wolfpack leader appears as the Field Programmable Gate Arrays, or shortly FPGA and it is taking over very fast.

The only issue here is the boards are difficult to find each passing month.

Disclaimer: this post is not sponsored by any company nor have any referral links.

 

Let’s look at why FPGA is interesting for mining.

The Two Main Issues FPGA Are Meant to Solve Cryptocurrencies are volatile and unstable in the current market, August-2018. 

 

Cryptocurrency market have been jumping from Ethereum to Monero to Zcash, back and forth, depending on the volatility of coin profitability. 

The ASICs storming the mining pool strategy is to buy an ASIC miner and pray that it pays off in time. GPU mining  and the amount of coins you can mine is limited and people find this unsatisfactory 75% of the time.

The ASIC's issue is it offers zero flexibility when it comes to a single coin that can be mined and no other type of cryptocurrency coin. 

 

An ASIC is hard-wired to mine one algorithm type of coin only. 



Highest End, Lowest Cost:

Ultra96 is an Arm-based, Xilinx Zynq UltraScale+ MPSoC development board based on the Linaro 96Boards specification. 

The 96Boards’ specifications are open and define a standard board layout for development platforms that can be used by software application, hardware device, kernel, and other system software developers. 

 

Ultra96 represents a unique position in the 96Boards community with a wide range of potential peripherals and acceleration engines in the programmable logic that is not available from other offerings. 

Ultra96 boots from the provided Delkin 16 GB MicroSD card, pre-loaded with PetaLinux. 

 

Engineers have options of connecting to Ultra96 through a Webserver using integrated wireless access point capability or to use the provided PetaLinux desktop environment which can be viewed on the integrated Mini DisplayPort video output. 

 

Multiple application examples and on-board development options are provided as examples. 

 


Ultra96 provides four user-controllable LEDs. 

 

Engineers may also interact with the board through the 96Boards-compatible low-speed and high-speed expansion connectors by adding peripheral accessories such as those included in Seeed Studio’s Grove Starter Kit for 96Boards. 

 

Micron LPDDR4 memory provides 2 GB of RAM in a 512M x 32 configuration. Wireless options include 802.11b/g/n Wi-Fi and Bluetooth 4.2 (provides both Bluetooth Classic and Low Energy (BLE)). 

 

UARTs are accessible on a header as well as through the expansion connector. JTAG is available through a header (external USB-JTAG required). I2C is available through the expansion connector. 

 

 Ultra96 provides one upstream (device) and two downstream (host) USB 3.0 connections. A USB 2.0 downstream (host) interface is provided on the high speed expansion bus. 

 

Two Microchip USB3320 USB 2.0 ULPI Transceivers and one Microchip USB5744 4-Port SS/HS USB Controller Hub are specified. 

 

 The integrated power supply generates all on-board voltages from an external 12V supply (available as an accessory).



What’s the Third Option: There is always other option$. 

 

FPGA is the hardware taking over the market by storm. This is the new favorite in the cryptocurency mining community. 

 

FPGA have been around since 1979. 

 

They heavily used in science, vehicle modeling and even military deployment applications.

 

The first manufacturer of these devices is an American technology company called "Xilinx"

 

Years followed and another American company called Altera, (now owned by Intel), has joined the industry and has been the main Xilinx competitor since then.

 

The development of FPGA circuitboards have been welcomed very in many industries and the demand FPGA hardware technology is still booming. 

In 2013, the market for FPGA circuit boards was $6.1 billion and estimated $21.3 billion by year 2020.



Why FPGA Have not been used in cryptocurrency mining:

Since Bitcoin became popular, average people tried to mine with FPGA, but failed because they did not have the programming skill sets to utilize the FPGA circuit-boards.

 

The only people have mined FPGA circuit-boards were large mining exchanges, and they kept the FPGA circuit boards a secret for years.

 

When the first open source FPGA Bitcoin miner was released from private sectors until May 20, 2011. 




Juan Antonio Ernesto's Great Adventure:

A man named Juan Antonio Ernesto's, [his named was changed here to protect his immigration innocence], from Tijuana Mexico, who illegally migrated into Canada from Mexico, and was hired by Canada's silicon-valley, (in Waterloo Ontario).

After three years Juan left Canada, because of bias Canadian in that country, so Juan Antonio said, he had to leave to U.S..

When Juan entered the U.S. he was immediately granted citizenship by the U.S. government, because enrolled into U.S. college for free and acquired his CS-masters degree from NMT Socorro New-Mexico under his real name.

While he was in Socorro NM he and other Mexicans-Americans secretly managed the cryptocurrency mining software exchanged named "Macho-Rio-Grande".

The Mexican trio enabled the FPGA Xilinux cards workable and online usable for cryptocurrency mining.

The trio secretly made millions of dollars and they were the only private-public sector aware of this technology.

When Juan returned with millions of dollars of wealth to share with his friends in Canada he died from a fatal gunshot wound by MS13 in Vancouver Canada on the highway of tears.

Juan's bank accounts and cryptocurrencies was transferred before his death never to be found again.

Juan's friends ran to Mexico with the FPGA software technology and where also found dead months later and their accounts where all transferred the same.

All deaths related to these events where determined suicide, and the mystery of their deaths continues as everyone suspects MS13 hackers.

NOW, there are three reasons why FPGA circuit-boards have never really made it to the masses until today and the above mentioned is the first.

The Reason #1, is the lacking of non-programmable flexibility and software to architecture specifics. 

FPGA boards are not easy to software program, and they can be programmed to mine cryptocurrency. 

In order to use a FPGA board you must have hardware and software programming abilities.

The GPU works differently and the only changes enabled is to tweak the clock speed, and mining software.

The FPGA circuit-board has got to be programmed in raw-code from scratch in order to mine cryptocurrency. Writing the code in Verilog or VHDL language -and– neither Python nor C++ works, but only Verilog or VHDL languages.

Only dedicated programmers are capable managing this task from beginning equation to end resolved solution.

The Reason #2, is the creation of the first ASIC for mining cryptocurrencies, Unlike FPGA, was an ASIC hard-coded as a plug and play hardware only and not reprogrammable. 

Anyone can use an ASIC Miner-Box. There were a lot of alternatives to ASIC mining-box. Computer programmers have had the option of the GPU rigs and resolved into mining lesser coins than an FPGA circuit-board capable of.

The ASIC miner-box's are dominating the mining pools and Personal Computer Graphic Card GPU's are now less used technology.

The FPGA are becoming the average miner hardware these days.

There are several reasons FPGA are way faster. 


The FPGA circuit-board cards perform 3x to 100x times more efficient than GPU while having the same wattage power voltage draw saving hundred$

Depending on the algorithm matched to bitcoin, FPGA never fall behind ASICs miner-box's.

Upsides of FPGA

+ Compatibility for all mining currencies provided you are a  flexibility with Verilog or VHDL programming languages, or have partnered up with a programmer regards all cryptocurrency mining algorithms. There are no soft-forks affecting mining operations provided the programmer updates FPGA bitstream.

+ Extreme power efficiency compared to CPU's and GPUs.

Downsides of FPGA

+ FPGA have to be plugged into operational computers, just like GPUs.

+ Xilinux Vertex FPGA available to the mainstream for now (there are some exceptions though, which is why this article exists, more on that below).

+ Are quite pricey compared to GPUs.

+ Can be slightly outperformed by ASICs depending on the algorithm.

Bitstream:

The Bitstream is the program written on a low-level programming language known as Verilog or VHDL that tells the FPGA what to do.

If you want to mine a specific algorithm you must have a bitstream that tells the FPGA how to mine that specific algo.

Bitstreams are loaded to the FPGA once the system boots. The bitstream is loaded into the volatile FPGA RAM memory. This is the same DDR4 memory – the FPGA model people use for mining has got 64GB of it. 

This huge amount of RAM allows the FPGA to store hundreds of bitstreams and switch between those in fractions of a second.

This functionality allows an FPGA to mine algorithms such as Timetravel10, X11Evo, X16R and X16S that require the chip to switch between various “lesser” hashing algorithms every few minutes.

While the bitstream can be changed in a fraction of a second, the board can still mine only one algorithm at a time with a couple rare exceptions.

Anyone can create bitstreams for existing mining algos and Zetheron (name of the company) will be collecting a fixed fee on behalf of the developers. This will ensure:

  • safety to the developers of bitstreams – they will get paid for their work and

  • no entry fee for FPGA owners – you pay only if the bitstream you have downloaded works

  • Plus, the access to a diversity of community-made bitstream will certainly guarantee that we will be able to mine virtually any algo and fork we want.

As for today, Zethereon has working bitstream for Cryptonote and Lyra2z algos. “The current plan is to release approximately one algorithm per month, until all major algorithms in the above table have been covered.”  – Zetheron writes. Here is a table of all the planned coins for the VU9P FPGA.

This means that thanks to the work those guys did, we will now have a seamless, pretty much plug-and-play experience when using our FPGA boards.

The ecosystem Zetheron is creating will give us all the bitstream solutions we need to mine any popular algorithm we want without the need to know anything about programming. Plus, developers will be motivated to push the plank higher and create better bitstreams.

Squirrels Research Labs and BittWare Launch World's Most Powerful Cryptocurrency FPGA Card.


(NORTH CANTON, Ohio, Sept. 07, 2018 (GLOBE NEWSWIRE via COMTEX)

 --- Squirrels Research Labs (SQRL) recently partnered with BittWare, a Molex company and provider of high-performance computer boards, to offer the world's most powerful FPGA cryptocurrency mining hardware, the BittWare CVP-13.

The CVP-13 uses the largest Virtex UltraScale+ FPGA chip available from Xilinx Inc. XLNX, -1.10%

"By utilizing the largest chip available from Xilinx, the VU13P, BittWare's CVP-13 offers the most powerful cryptocurrency FPGA card in existence," SQRL president David Stanfill said.

The CVP-13 provides the most processing power of any FPGA cryptocurrency mining card available--46 percent more logic, 31 percent more on-chip memory and a 66 percent larger power supply than other popular boards that use the Xilinx VU9P FPGA chip.

























Unlike other FPGA mining hardware in the market, the CVP-13 uses a 300 ampere power supply, allowing users to maximize the potential of the VU13P FPGA chip on the board.

Similar hardware in the market requires tuning that pulls more power than the hardware is rated for, causing efficiency losses.

The CVP-13's factory-designed and installed Viper cooling options include liquid cooling to increase efficiency.

"The efficiency and power gains obtained with the CVP-13 allow for higher density deployments with less hosting overhead," Stanfill explained.

"For every three VU9P-based boards, you only need two CVP-13 units to achieve similar performance goals."

In addition to cooler and more efficient performance, the increased amount of on-chip logic allows larger algorithms to fit that aren't available on other hardware. These algorithms include X17r, X16r and TimeTravel10.

CVP-13 cards can be chained together with QSFP28 and SlimSAS cables, enabling them to run larger algorithms like Equihash variants.

The CVP-13 has quadruple the amount of bandwidth of competitive cards and includes four QSFP28 cages and two SlimSAS connectors for board-to-board communication.

The CVP-13 includes the ability to run secure bitstreams developed and supported by AllMine Inc., and SQRL.

"BittWare has been producing high-end boards for three decades," Stanfill continued.

"They're a well-known and respected brand in the FPGA industry and now have the strength of Molex for even stronger market agility to take on projects like this."

BittWare CVP-13 FPGA boards are available for purchase now through SQRL with deliveries expected in November. Hosted CVP-13 hardware is also available through The Mineority Group.

Both options can be purchased at http://store.mineority.io.

"We're very excited to continue bringing groundbreaking FPGA technology into this market," Stanfill said.

Xilinx Virtex-7 2000T FPGA provides over 20 million ASIC gates per-chip Date: 09m-24d-2018y, the present purchase cost of a Xilinx XC7V2000T Chip is $1k.




Xilinx has announced the first shipments of its Virtex-7 2000T Field Programmable Gate Array (FPGA). The Virtex-7 2000T is the world’s highest-capacity programmable logic device – it contains 6.8 billion transistors, providing customers access to 2 million logic cells.

This is equivalent to 20 million ASIC gates, which makes these devices ideal for system integration, ASIC replacement, and ASIC prototyping and emulation.

This capacity is made possible by Xilinx’s Stacked Silicon Interconnect technology – also referred to as 2.5D ICs. The simplest packaging technology is to have a single die in the package.

The next step up the “complexity ladder” is to have multiple die is the same package, but for all of these die to be attached directly to the package substrate. In this case, compared to the tracks on the die, the tracks on the package substrate are relatively large, slow, and driving signals onto them consumes a lot of power.

In this first incarnation of the technology, four FPGA die are attached to the silicon interposer, which – in addition to connecting the FPGAs to each other – provides connections to the package as illustrated below.


In the case of the Virtex-7 2000T, the FPGA die are implemented at the 28 nm technology node, while the passive silicon interposer is implemented at the 65 nm technology node. Implementing the large silicon interposer at this higher node reduces costs and increases yield without significantly degrading performance.

One way to think about this is that the silicon interposer essentially adds four additional tracking layers that can be used to connect the FPGAs to each other with more than 10,000 connections between each pair of adjacent die!

On top of this, Through-Silicon Vias (TSVs) are used to pass signals through the silicon interposer to C4 bumps on the bottom of the interposer. These bumps are then used to connect the interposer to the package substrate.


A view of Xilinx’s Virtex-7 2000T device showing the
packaging substrate (bottom), silicon interposer (middle),
and four FPGA die (top).


Compared with having to use standard I/O connections to integrate two FPGAs together on a circuit board, this stacked silicon interconnect technology is said to provide over 100X the die-to-die connectivity bandwidth-per-watt, at one-fifth the latency, without consuming any of the FPGAs' high-speed serial or parallel I/O resources.

Of particular interest to designers is the fact that, despite being composed of four die, the Virtex-7 2000T preserves the traditional FPGA use model in that users will program the device as one extremely large FPGA with the Xilinx tool flow and methodology.

Xilinx’s first application of 2.5D IC stacking gives customers twice the capacity of competing devices and leaps ahead of what Moore’s Law could otherwise offer in a monolithic 28-nanometer (nm) FPGA.

Xilinx says that its customers can use Virtex-7 2000T FPGAs to replace large capacity ASICs to achieve overall comparable total costs in a third of the time, creating integrated systems that increase system bandwidth and reduce power by eliminating I/O interconnect, and accelerating the prototyping and emulation of advanced ASIC systems.

device,
the world’s highest-capacity FPGA using
Stacked Silicon Interconnect technology.


 “The Virtex-7 2000T FPGA marks a major milestone in Xilinx’s history of innovation and industry collaboration,” said Victor Peng, Xilinx Senior Vice President, Programmable Platforms Development.  

“Of significance to our customers is the fact that Stacked Silicon Interconnect technology offers capacities that otherwise wouldn’t be possible in an FPGA for at least another process generation. 

They can immediately add new functionality to existing designs while forgoing an ASIC, cost reduce a 3 or 5 FPGA solution into a single FPGA or move ahead with prototyping and building system emulators using our largest FPGAs at least a year earlier than typical for a new generation.”


The Virtex-7 2000T device also provides equipment manufacturers with an integration platform that will help them overcome the challenges of lowering power while increasing performance and capabilities.

By eliminating the I/O interfaces between different ICs on a circuit board, a system’s overall power consumption can be reduced considerably.

Consider the following example provided by Xilinx that compares a single Virtex-7 2000T with four of the largest monolithic ICs as illustrated below:


Actually, this is not really a fair comparison, because in terms of capacity the Virtex-7 2000T is equivalent to only around two of the largest monolithic ICs. But even comparing to two monolithic ICs results in a significant power advantage. (Having said this, I’d be interested to know just what was being exercised in this example – Logic? Memory? DSP slices? SERDES channels? – and at what frequency.)

FPGA programming step by step...


FPGAs and microprocessors are more similar than you may think. Here's a primer on how to program an FPGA and some reasons why you'd want to. Small processors are, by far, the largest selling class of computers and form the basis of many embedded systems. The first single-chip microprocessors contained approximately 10,000 gates of logic and 10,000 bits of memory. Today, field programmable gate arrays (FPGAs) provide single chips approaching 10 million gates of logic and 10 million bits of memory. Figure 1 compares one of these microprocessors with an FPGA.

Powerful tools exist to program these powerful chips. Unlike microprocessors, not only the memory bits, but also the logical gates are under your control as the programmer. This article will show the programming process used for FPGA design.
As an embedded systems programmer, you're aware of the development processes used with microprocessors. The development process for FPGAs is similar enough that you'll have no problem understanding it but sufficiently different that you'll have to think differently to use it well. We'll use the similarities to understand the basics, then discuss the differences and how to think about them.
Similarities
Table 1 shows the steps involved in designing embedded systems with a microprocessor and an FPGA. This side-by-side comparison lets you quickly assess the two processes and see how similar they are.
