ispGDX80VA
Architecture
The ispGDXVA architecture is different from traditional
PLD architectures, in keeping with its unique application
focus. The block diagram is shown below. The program-
mable interconnect consists of a single Global Routing
Pool (GRP). Unlike ispLSI devices, there are no pro-
grammable logic arrays on the device. Control signals for
OEs, Clocks/Clock Enables and MUX Controls must
come from designated sets of I/O pins. The polarity of
these signals can be independently programmed in each
I/O cell.
Each I/O cell drives a unique pin. The OE control for each
I/O pin is independent and may be driven via the GRP by
one of the designated I/O pins (I/O-OE set). The I/O-OE
set consists of 25% of the total I/O pins. Boundary Scan
test is supported by dedicated registers at each I/O pin.
In-system programming is accomplished through the
standard Boundary Scan protocol.
The various I/O pin sets are also shown in the block
diagram below. The A, B, C, and D I/O pins are grouped
together with one group per side.
I/O Architecture
Each I/O cell contains a 4:1 dynamic MUX controlled by
two select lines as well as a 4x4 crossbar switch con-
trolled by software for increased routing flexiability (Figure
1). The four data inputs to the MUX (called M0, M1, M2,
and M3) come from I/O signals in the GRP and/or
adjacent I/O cells. Each MUX data input can access one
quarter of the total I/Os. For example, in an 80-I/O
ispGDXVA, each data input can connect to one of 20 I/O
pins. MUX0 and MUX1 can be driven by designated I/O
pins called MUXsel1 and MUXsel2. Each MUXsel input
covers 25% of the total I/O pins (e.g. 20 out of 80). MUX0
and MUX1 can be driven from either MUXsel1 or MUXsel2.
