Hand-tracking Anti Tetris game on DE2 board

Monday, May 27th, 2013

Tian Gao from Cornell's University's EE program developed what he calls an AntiTetris game using the Altera DE2 FPGA board. The project was part of the final requirements in Cornell's ECE 5760 Advanced Microcontroller Design and system-on-chip Spring 2013 course. "In this project, I built a video game "Anti Tetris"...

Homebrew Cray-1A on Xilinx Spartan-3E board

Thursday, March 7th, 2013

Chris Fenton has spent the last year and a half or so constructing his own 1/10-scale, binary-compatible, cycle-accurate Cray-1. He says this project falls purely into the “because I can!” category." The actual design was implemented in a Xilinx Spartan-3E 1600 development board. For vintage computing enthusiasts, Chris also provides...

Understanding Verilog warnings

Friday, September 23rd, 2011

Big Mess o’ Wires has a review of Verilog warnings: Those of you who’ve followed the blog for a while know about my many frustrations with Verilog. Because it feels sort of a like a procedural programming language, but very definitely isn’t one, I keep expecting to be far more...
