ispLSI 5000VE 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 pro-
vided 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 by-
passed 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.
