The parallel data is acquired through the parallel data acquisition port
(PDAP) which provides a means of moving high bandwidth data to the
core's memory space. The data may be sent to memory as one 32-bit word
per input clock cycle or packed together (for up to four clock cycles worth
of data).
Figure 11-1
provides a graphical overview of the input data port architec-
ture. Notice that each channel is independent and contains a separate
clock and frame sync input.
The IDP provides an easy way to pump serial data into on-chip
memory since it is less complex than the traditional SPORT mod-
ule, limited to unidirectional slave transfers only.
