• Questions on ADSP-21489

    Hi

    I am trying to port some speech processing algorithms on  ADSP-21489, have below questions. Using ADSP-21489 EZ-Board for testing purpose.

    1. Does  ADSP-21489 has data cache? when I tried to read/write from external memory, it takes 30 odd cycles whereas the…

  • RE: When ADSP-21489 is doing FFT, can it take any number of points?

    Note: the accel_cfft function mentioned here is not supported on the ADSP-21489. It requires the fft hardware accelerator found on the SHARC+ platform (ADSP-2158x / ADSP-SC58X).

  • ADSP-21489 display

    I would like to know if a dsp chip like the ADSP-21489 can be connected directly to a touch screen display, encoders and buttons or it is necessary a second microprocessor for these functions ?

    Is it somehow possible to connect push buttons for ADSP-21489?

  • ADSP-21489 Watchdog Timer with external oscillator WDTRSTO# is always LOW

    Hello, in our custom board with ADSP-21489 DSP after power up WDTRSTO# pin output is always LOW (asserted).

    I disconnect the pin from the rest of the circuit (by removing R6) so the pin is floating and I am expecting a HIGH level as soon as the DSP power…
