The GPLD
The structure of the General Purpose PLD consists of a programmable AND ARRAY
and 2 sets of I/O Macrocells. The ARRAY has 37 input signals, same as the DPLD.
From these inputs, “ANDed” functions are generated as product term inputs to the
macrocells. The I/O Macrocell sets are named after the I/O Ports they are linked to,
e.g., the macrocells connected to Port B are named PB Macrocells. The PB macrocells
are registered macrocells with D-type flip-flops, where PA consists of combinatorial
macrocells.
PA Macrocell Structure
Figure 6 shows the PA Macrocell block, which consists of 8 identical combinatorial
macrocells. Each macrocell output can be connected to its own I/O pin on Port A.
There is one user programmable global product term that is output from the GPLD’s
AND ARRAY which is shared by all the macrocells in Port A:
J
PA.OE
Enable or tri-state Port A output pins
The circuit of a PA Macrocell is shown in Figure 7. There are 4 product terms from the
GPLD’s AND ARRAY as inputs to the macrocell. Users can select the polarity of the
output, and configure the macrocell to operate as:
J
GPLD Input
Use Port A pin as dedicated input
J
GPLD Output
Use Port A pin as dedicated output
