2.3.4 Bandwidth and Latency Requirements
The format in memory for both little and big-endian byte ordering is shown in
Normally, the rate of transmission of frames corresponds exactly to the source
sampling frequency. The maximum latency requirement will be for 96 kHz streams
(i.e. frame rate = 96 kHz) with the SPDIF Input input set up for any of the 32-bit
capture modes:
(96K frames/sec) x (8bytes/ frame) = 0.768Mbytes/sec
The maximum latency allowed in order to sustain this transfer rate is (assuming data
transfers are 64 bytes each):
64 bytes/N sec= 0.768 Mbytes/sec
Solving for N and providing a relation,
For error-free operation during sustained DMA, there needs to be one 64 byte DMA
write transfer completed to memory every 83 usecs. This guarantees the latency
requirement for the worst case input sample rate. If the latency requirement is not
met, the hardware sets the HBE bit in the SPDI_STATUS register to logic ‘1’
indicating a bandwidth error. For this condition, one or more audio samples have
been lost and are not recoverable. The bus arbitration for the SPDIF Input input block
should be adjusted by the user to satisfy this latency requirement. Refer to section
