ispLSI 5000V Description
The ispLSI 5000V Family of In-System Programmable High Density Logic Devices is based on Generic Logic Blocks GLBs of 32 registered macrocells and a single Global Routing Pool GRP structure interconnecting the GLBs.
Outputs from the GLBs drive the Global Routing Pool GRP between the GLBs. Switching resources are provided to allow signals in the Global Routing Pool to drive any or all the GLBs in the device. This mechanism allows fast, efficient connections across the entire device.
