• ADSP-21571 Interface to FPGA

    Hello, I'm still using the TigerSharc ADSP-201 DSP and interface to an FPGA over the external Data/Address bus. The interfacing to FPGA was very easy and very powerful using the Pipeline protocol. I was looking at the latest Sharc processor and foudn…

  • Implementing GIGE UDP on ADSP-21571?

    Hello, I was wondering if there are any example code for the ADSP-21571 that implements GIGE using UDP packets?

    Do you need an real-time operating system?



  • ADSP-21571 SPI Slave Boot problem


    I'm trying to boot an ADSP-21571 using SPI Slave mode, but I just can't get it to work.
    I'm pretty sure I have configured my SPI Master correctly (msb-first, pos. clk polarity). At the moment I'm running at a very low rate (1MHz).

  • ADSP-21571: Linkport DMA bandwidth control or similar

    Hi all,

    I'm receiving 32-bit data over the Linkport. The Linkport FIFO is emptied by the Linkport DMA (DMA36 for ADSP-21571).

    Now, I need to briefly stop the DMA/Linkport. Is there an easy to do this? Using the DMA (or Linkport) enable bits (in corresponding…

  • ADSP-21571/ICE-2000: Not able to connect to target


    I'm trying to debug a custom board with two ADSP-21571 and one ADSP-21489.

    As I am focusing on debugging the 21571s I've marked the 21489 as "Unknown" in the Target Configurator (I'm new to CCES, but I get the feeling you cannot debug different…

  • (ADSP-21571)About SPI(non-DMA) TFIFO


    I use SPI0 (slave) with non-DMA.
