Description
The ispLSI 1032 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 pro-
vides complete interconnectivity between all of these
elements. The ispLSI 1032 features 5-Volt in-system
programming and in-system diagnostic capabilities. It is
the first device which offers non-volatile reprogrammability
of the logic, as well as the interconnect to provide truly
reconfigurable systems.
The basic unit of logic on the ispLSI 1032 device is the
Generic Logic Block (GLB). The GLBs are labeled A0, A1
.. D7 (see figure 1). There are a total of 32 GLBs in the
ispLSI 1032 device. Each GLB has 18 inputs, a program-
mable AND/OR/XOR array, and four outputs 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
other GLB on the device.
