The PSD5XX
Architecture
PSD5XX consists of seven major functional blocks:
The functions of each block are described in the following sections. Many of the blocks
perform multiple functions, and are user configurable. The chip configurations are specified
by the user in the PSDsoft Development Software; some are specified by setting up the
appropriate bits in the configuration registers during run time.
9.1 ZPLD Block
Key Features
General Description
The ZPLD block has 3 embedded PLD devices:
Figure 4 shows the architecture of the ZPLD. The PLD devices all share the same
input bus. The true or complement of the 61 input signals are fed to the programmable
AND-ARRAY. Names and source of the input signals are shown in Table 3. The PA, PB, PE
signals, depending on user configuration, can either be macrocell feedbacks or inputs from
Port A, B or E.
