Product Term Sharing Array
The Product Term Sharing Array (PTSA) consists of 32 inputs from the Dual-OR Array and 32 outputs directly to
the macrocells. Each output is the OR term of any combination of the seven PTSA OR terms connected to that out-
put. Every Nth macrocell is connected to N-3, N-2, N-1, N, N+1, N+2, and N+3 PTSA OR terms via a programma-
ble connection. Figure 4 shows the graphical representation of the PTSA.
