[Coco] Learning CPU Architecture and Digital Design

[Bob Devries]

Hi all,

the December 2012 issue of Elektor magazine has an article entitled "Taming 
the Beast - A simplified approach to working with FPGAs"

They have designed a development board based on the XILINX SPARTAN 
XC3S250E-4VQG100C. The board is just 65 x 25mm, and appears to the host PC 
as an intelligent USB stick.

Have you seen this Mark? Comments?
