描述 Description

The ispLSI 8000V Family of Register-Intensive, 3.3V SuperBIG In-System Programmable Logic Devices is based on Big Fast Megablocks of 120 registered macrocells 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.
