Description
— Reprogram Soldered Devices for Faster Prototyping
The ispLSI 1032E is a High Density Programmable Logic
Device containing 192 Registers, 64 Universal I/O pins,
eight Dedicated Input pins, four Dedicated Clock Input
pins and a Global Routing Pool (GRP). The GRP
provides complete interconnectivity between all of these
elements. The ispLSI 1032E device offers 5V non-vola-
tile in-system programmability of the logic, as well as the
interconnects to provide truly reconfigurable systems. A
functional superset of the ispLSI 1032 architecture, the
ispLSI 1032E device adds two new global output enable
pins.

The basic unit of logic on the ispLSI 1032E device is the
Generic Logic Block (GLB). The GLBs are labeled A0,
A1…D7(seeFigure1). Thereareatotalof32GLBsinthe
ispLSI 1032E device. Each GLB has 18 inputs, a pro-
grammableAND/OR/ExclusiveORarray,andfouroutputs
which can be configured to be either combinatorial or
registered. Inputs to the GLB come from the GRP and
dedicated inputs. All of the GLB outputs are brought back
into the GRP so that they can be connected to the inputs
of any GLB on the device.
