pins, four 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 1032EA features 5V in-system
programmability (ISP鈩? and in-system diagnostic capa-
bilities via IEEE 1149.1 Test Access Port. The ispLSI
1032EA device offers non-volatile reprogrammability of
the logic, as well as the interconnects to provide truly
reconfigurable systems. A functional superset of the
ispLSI 1032 architecture, the ispLSI 1032EA device adds
user selectable 3.3V or 5V I/O and open-drain output
options.
The basic unit of logic on the ispLSI 1032EA device is the
Generic Logic Block (GLB). The GLBs are labeled A0,
A1鈥7 (Figure 1). There are a total of 32 GLBs in the
ispLSI 1032EA device. Each GLB has 18 inputs, a
programmable AND/OR/Exclusive OR array, and four
outputs which can be configured to be either combinato-
rial 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.
