The ispLSI 8000V Family of Register-Intensive, 3.3V

SuperBIG In-System Programmable Logic Devices is

based on Big Fast Megablocks of 120 registered macro-

cells and a Global Routing Plane (GRP) structure

interconnecting the Big Fast Megablocks. Each Big Fast

Megablock contains 120 registered macrocells arranged

in six groups of 20, a group of 20 being referred to as a

Generic Logic Block, or GLB. Within the Big Fast

Megablock, a Big Fast Megablock Routing Pool (BRP)

interconnects the six GLBs to each other and to 24 Big

Fast Megablock I/O cells with optional I/O registers. The

Global Routing Plane which interconnects the Big Fast

Megablocks has additional global I/Os with optional I/O

registers. The 192-I/O version contains 72 Big Fast

Megablock I/Os and 120 global I/Os, while the 312-I/O

version contains 168 Big Fast Megablock I/Os and 144

global I/Os.
