General Description
The ZPLD block has 2 embedded PLD devices:
J
DPLD
The Address Decoding PLD, generating select signals to internal I/O or memory blocks.
J
GPLD
The General Purpose PLD provides 24 programmable macrocells for general
or complex logic implementation; dedicated to user application.
Figure 11 shows the architecture of the ZPLD. The PLD devices all share the same
input bus. The true or complement of the 59 input signals are fed to the programmable
AND-ARRAY. Names and source of the input signals are shown in Table 4. The PA, PB, PE
signals, depending on user configuration, can either be macrocell feedbacks or inputs from
Port A, B or E.
