Pin Out Diagram - Bottom View (84pin PGA - AC84)
The PDSP16540 is designed for use in synchronous data
flow systems in which the transfer between system elements
is contolled by a continuously available system clock. This
system clock is usually at the maximum rate that the system
elements will allow, since it is governing the rate at which
processing can be performed on the acquired data. The rate
at which external data is actually inputed to the system ( the
sampling rate in DSP terminology ) is usually much slower
than the internal system, or computational, rate. The
PDSP16540 then provides a reservoir for data which is
acquired at the sampling rate and then processed with the
higher speed system clock rate.
Data is written to the RAM using an asynchronous write
strobe when a write enable input is active. The enbling signal
must meet the set up and hold times given in Table 1. Data is
read from the RAM using a read strobe which is expected to
be continuously availble and not to just go active when read
operations are actually needed. It is normally the high speed
system clock discussed earlier. All RAM addresses are
generated internally since the device is partitioning consecu-
