The VCP1 and VCP2 contain several memory-mapped registers accessible by the CPU, and the EDMA module. A configuration-bus access is faster than an EDMA-bus access for isolated accesses (typically when accessing control registers). EDMA-bus accesses are used for EDMA transfers and provide maximum throughput to/from the VCP modules. The registers are listed in Table 32-29 and Table 32-30 .
The branch metric and traceback decision memories contents are not accessible and the memories can be regarded as FIFOs by the DSP, no indexing on addresses need to be performed.
