Data Transfer
The data from each of the eight IDP channels is inserted into an eight reg-
ister deep FIFO, which can only be transferred to the core's memory space
sequentially. Data is moved into the FIFO as soon as it is fully received.
One of two methods can be used to move data from the IDP FIFO to
internal memory:
• The core can remove data from the FIFO manually. This method
of moving data from the IDP FIFO is described in the next section,
"Core Transfers" on page
• Eight dedicated DMA channels can sort and transfer data. This
method of moving data from the IDP FIFO is described in
Transfers" on page
Data Buffer
The register provides information about the output of the
IDP_FIFO
8-deep IDP FIFO which have been filled by the SIP or the PDAP units.
Normally, this register is used only to read and remove the top sample
from the FIFO. Channel encoding provides for eight serial input types
that correspond to the
using channels 0–7 in serial mode, this register format applies. When
using channel 0 in parallel mode, refer to the description of the packing
bits for PDAP mode.
