    I submitted the same question…

  • RE: I need help about adsp-21584 spi2.


    The L1 Private Memory space of SHARC+ can be accessed directly by itself without adding any offset. In order to access internal memories from another SHARC core/ARM core or other peripheral DMA/Memory-to-memory DMA an offset (multiprocessor offset…

  • How can I boot an ADSP-21584 based SHARC application on an ADSP-SC584 part?

    Since the ADSP-SC584 part expects ARM to boot up first, we may still need to use an ADSP-SC584 dummy ARM core project to generate the loader file. The dummy ARM project is required to bring the SHARC cores out of reset during booting. The code runs…

  • Late frame sync loopback SPORT (ADSP-21584)


    We are using the DAI SPORT on the ADSP-21584 to connect to some temperature sensors (ADS1120IPWR). We noticed when using late frame sync we weren't reading back any information (with early frame sync we were getting back something). We set up…
