• ADSP-21488 SPI TX Slave Multiple 32bit Values

    I have found that when configuring the ADSP-21488 SPI for transmission in slave mode to send multiple 32-bit values (in my case four) that the TXS flag does not behave properly unless the master toggles the chip select after each value. This is the same…

  • Inquiries about Sample rate converter of ADSP-21488

    Hi All,

    I have a question about ADSP-21488.

    There are the following two product numbers for this model number.

    ・ ADSP-21488KSWZ-4B

  • Bootloader Project for ADSP-21488

    Hi,

    We're using ADSP-21488 in one of our products. We wanted this processor to boot from the Flash. In our prototype board we connected the SPI lines as follows:

    DPI_P01 -> SPI0_MISO

    DPI_P02 -> SPI0_CLK

    DPI_P03 -> SPI0_MOSI

    We made sure…

  • Masking the SPORT2 interrupt on ADSP-21488 doesn't prevent the interrupt from being serviced

    Hi Folks

    On ADSP-21488, masking the SPORT2 interrupt by using asm("bit clr IMASK P7I;"); doesn't seem to prevent the interrupt from being serviced.

    Also, if I single step while watching the value of IMASK in a register window in VDSP, I…

  • 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…
  • 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
    and only…

  • How IIR accelerator on ADSP-SC58x/ADSP-2158x is different than the FIR accelerator on ADSP-214xx?

    The IIR accelerator on ADSP-SC58x/ADSP-2158x works exactly in the same manner except the following differences:

    • Unlike in ADSP-214xx, you don't need to enable the IIR accelerator in PMCTL1 register explicitly in ADSP-SC58x/ADSP-2158x. In fact…
