Description
The ispLSI 1024/883 is a High-Density Programmable
Logic Device processed in full compliance to MIL-STD-
883. This military grade device contains 144 Registers,
48 Universal I/O pins, six 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 1024/883
features 5-Volt in-system programmability 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 1024/883 device is
the Generic Logic Block (GLB). The GLBs are labeled A0,
A1 .. C7 (see figure 1). There are a total of 24 GLBs in the
ispLSI 1024/883 device. Each GLB has 18 inputs, a
programmable 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.
