Who Could Possibly Need An FPGA with 9M Logic Cells and 35B Transistors?

Xilinx recently announced the Virtex UltraScale+ VU19P FPGA. Of course, FPGA companies announce new chips every day. The reason this one caught our attention is the size of it: nearly 9 million logic cells and 35 billion transistors on a chip! If that’s not enough there is also over 2,000 …read more

Smoothieboard Gets An Ambitious Update For V2

If you’ve been reading Hackaday for awhile, there’s an excellent chance you’ve seen a project or two powered by the Smoothieboard. The open source controller took Kickstarter by storm in 2013, promising to be the last word in CNC thanks to its powerful 32-bit ARM processor. Since then we’ve seen …read more

This LED Cube Is One Heck Of An ICEBreaker

Like the tastes of the makers that build them, LED cubes come in all shapes and sizes. From the simplest 3x3x3 microcontroller test, to fancier bespoke installations, they’re a great way to learn a bunch of useful embedded techniques and show off at the same time. [kbob] has done exactly …read more

LED Driver Board Could Be Your Ticket To FPGA Development

Microcontrollers are a great way to learn about developing for embedded systems. However, once you outgrow their capabilities, FPGAs bring muscle that’s hard for even the fastest-clocked micros to match. If you’re doing anything with high-speed signals, loads of RAM, or something that requires lots of parallel calculation, you can’t …read more

XFM: A 32-Voice Polyphonic FM Synthesizer On An FPGA

There’s something about Frequency Modulation (FM) synthesizer chips that appeals to a large audience. That’s one of the reasons behind [René Ceballos]’s XFM project, aiming to duplicate on an FPGA the sound of pure-FM synthesizer chips of the past such as the Yamaha DX series, OPL chip series …read more

Bringing FPGA Development To The Masses

The Field Programmable Gate Array (FPGA) is one of the most exciting tools in the modern hacker’s arsenal. If you can master the FPGA, you can create hardware devices that not only morph and change based on your current needs, but can power through repetitive tasks at phenomenal rates. The …read more

Yo Dawg, I Heard You Like FPGAs

When the only tool you have is a hammer, all problems look like nails. And if your goal is to emulate the behavior of an FPGA but your only tools are FPGAs, then your nail-and-hammer issue starts getting a little bit interesting. That’s at least what a group of students …read more

FPGA Soft CPU is Superscalar

We will admit it: mostly when we see a homebrew CPU design on an FPGA, it is a simple design that wouldn’t raise any eyebrows in the 1970s or 1980s. Not so with [Henry Wong’s] design, though. His x86-like design does superscalar out-of-order execution, just like big commercial modern CPUs. …read more

A Modular Logic Analyzer For FPGAs

When working on a project, it’s incredibly helpful to be able to visualize the various signals in play. This is important when attempting to determine if what is supposed to be happening is actually happening. However, logic analyzers can be expensive, so a group from [Bruce Land]’s ECE5760 class developed …read more

PokerBot Uses FPGA For Card Calculating Horsepower

Played against humans, Poker is a game as much about reading your opponent as it is about the cards you’re dealt. That doesn’t mean there aren’t certain mathematical ways to aid your decision making based on probabilities. In this vein, a group of students from Cornell’s ECE 5760 class built …read more
