IRAM Test Board James Beck ( )
Why Build Demo Hardware? Good proof of correct design Puts constraints on chip designers Best way to discover some things System design teaching tool Gee-whiz factor PR DARPA wants it
Chip Testbed Requirements Socketed IRAM chip Easy probing; debug signals available Adjustable frequency & voltage Thermal control Easy development environment
Marching Orders IRAM Accessible over the Web Development/test framework
