• ADSP-21478 SPI slave boot issues


    I am having some problems getting my ADSP-21478 SHARC processor to execute a boot kernel in SPI Slave boot mode.

    Initially, I performed some tests using the standard 21479.asm boot kernel, but for debugging purposes I created a custom boot kernel…

  • ADSP-21478 slave boot handshake


    I'm using host processor to boot ADSP-21478. I have a problem because i need to add delays between sent words to boot DSP correctly. I would like to use MISO pin for handshake, but the state of this pin remains unchanged (pullup and pulldown resistors…

  • IDP of ADSP-21478

    Want to use the IDP of SHARC to combine 8 I2S input channels to generate one TDM output.

    However, there is only 20 DAI pins, how do we rout the 24 input signal pins (CLK, FS, DATA) of eight SPORT (each input I2S has same clock frequency, but not synchronous…
  • SPORT DMA simulator problem using adsp-21478


    I am trying to use the simulator for the 21478 to verify the SPORT DMA with streams. I modified one of my existing programs I originally wrote for the 21065L. Before I modified it, I checked it again using the simulator in VisualDSP 5.1 and it worked…

  • TCB block of fir accelerator from example in BSP of ADSP-21478


    In the Multi_Iteration_Mode example

    TCB block for the fir accelerator is mentioned in one order and the TCB block defined in its reverse order.

    And it will work only if we follow the code similarly, why we have to follow in this order??

    And do…

  • How FFT accelerator (FFTA) on ADSP-SC58x/ADSP-2158x is different as compared to ADSP-214xx processors / What are the major features of FFTA on ADSP-SC58x/ADSP-2158x ?

    FFT Accelerator on ADSP-SC58x/ADSP-2158x is a completely new design as compared to the FFT accelerator on ADSP-214xx processors. The major differences/features of the FFT accelerator on ADSPSC58x/ADSP-2158x are:

    • Unlike in ADSP-214xx, the…
  • Porting software  from ADSP-21489 to ADSP-21573 and ADSP-SC573 

    Customer ask some questions.

    Right now we have  plenty of software for ADSP-21489, but it’s quite hard to port it to ADSP-SC573 family. Code itself

    is 99% C and C++.


    Does family ADSP-SC573 have interface with external static memory like AMI for ADSP…

  • prototyping the a ADSP-TS203S design with a ADSP-TS201s or a ADSP-TS202S

    We're currently laying out a prototype PCB to take an ADSP-TS203 TigerSHARC
    Processor (i.e. with only a 32 bit cluster bus and 2 link ports). Could we fit
    an ADSP-TS201/2 to this board if we constrict external bus access to 32 bits
