Hello, I hope at least one of you could me help to setup the ADSP-21160M to an AD1881A attached to SPORT1 for DMA of only data, I mean, just the PCM audio samples trhough the DMA engine, without the "side information" like the TAG PHASE and COMMAND ADDRESS and STATUS ADDRESS. What I want to do is having the DMA processor getting, say 1152 audio samples into the DSP memory with the DSP core processor crunching on the already stored 1152 audio samples. This way I can have more time for block processing, instead of having the time just between audio samples conversions. As far as I've read that "side information" is inherent to each dual- channel conversion on that AC'97 compliant CODEC. No way to get rid of it??? Thanks, JaaC |
AC97 CODEC to SHARC (ADSP-21160M <=> AD1881A)
