Description
The ispLSI and pLSI 1032E are High Density Program-
mable Logic Devices containing 192 Registers, 64
Universal I/O pins, eight Dedicated Input pins, four Dedi-
cated Clock Input pins and a Global Routing Pool (GRP).
The GRP provides complete interconnectivity between
all of these elements. The ispLSI 1032E features 5-Volt
in-system programmability and in-system diagnostic ca-
pabilities. The ispLSI 1032E device offers non-volatile
reprogrammability of the logic, as well as the intercon-
nects to provide truly reconfigurable systems. It is
architecturally and parametrically compatible to the pLSI
1032E device, but multiplexes four input pins to control
in-system programming. A functional superset of the
ispLSI and pLSI 1032 architecture, the ispLSI and pLSI
1032E devices add two new global output enable pins.
The basic unit of logic on the ispLSI and pLSI 1032E
devices 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 and pLSI 1032E devices. Each GLB
has 18 inputs, a programmable AND/OR/Exclusive OR
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 GLB on the device.
