Description

The ispLSI 5000VE 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.

Each GLB contains 32 macrocells and a fully populated,

programmable AND-array with 160 logic product terms

and three extra control product terms. The GLB has 68

inputs from the Global Routing Pool which are available

in both true and complement form for every product term.

The 160 product terms are grouped in 32 sets of five and

sent into a Product Term Sharing Array (PTSA) which

allows sharing up to a maximum of 35 product terms for

a single function. Alternatively, the PTSA can be bypassed

for functions of five product terms or less. The

three extra product terms are used for shared controls:

reset, clock, clock enable and output enable.
