• ADSP-21569 UART Interrupt Routine

    Hello Team,

    We are using ADSP-21569 part for our application development, for debugging purpose we are using UART communication. adi_uart_CoreWrite() and adi_uart_CoreRead() API are used for writing and reading the UART data, Please tell me how to use…

  • Use different RAM on ADSP-21569

    Hi,

    We are designing an audio system (firmware and board) that use ADSP-21569.

    The firmware is based on SigmaStudioForSHARC-SH-Rel4.5.0 Target demo for 21569.

    For hardware design I used ADZS-21569-EZ-KIT as a reference.
    This eval board use an 8Gb DDR3…

  • Microphone Input Using ADAU1977 With ADSP-21569-EZKIT

    Hi All,

    Can anyone refer me to an example of using the ADAu1977 for microphone input with the ADSP-21569-EZKIT? My team has successfully worked with audio coming from the RCA channels through the ADAU1979, however, we would live to get live microphone…

  • Power Supply PCB layout IC ADSP- 21569

  • ADSP-21569

    Hi,

    My company develops audio mixer applications based on the SHARC ADSP-2148x DSP. We use visualDSP++ and USB-ICE/ICE1000 for its development. Recently we came to know about the new 1GHz ADSP-21569 DSP. We are considering the possibility of migrating…
  • ADSP-21569 configure SPI2 as SigmaStudio interface instead of SPI1

    Hi,

    We are developing a project with 21569 and we will use SigmaStudioForSHARC 4.5 Target as a firmware in order to use SigmaStudio as top level audio application.

    Actually we are using the eval board but we have developed a custom board with an MCU connected…

  • ADSP-21569 Power ON Sequence

    Hello,

    What is the recommended Power ON Sequence for the device ADSP-21569.

    I am powering the device with the voltages VDD-INT (1V), VDD-DMC (1.35V), VDD-REF(1.8V), VDD-EXT (3.3V)

    With these voltages what is the power on sequence.

  • ADSP-21569 SigmaStudio and external memory usage for long delays

    Hi, 

    I'm working on a new design and we need to implement a new external delay custom algorithm in SigmaStudioForSHARC Rel4.5 for ADSP-21569.

    Our goal is to create a delay block that allows up to 2-second delay at 96Khz and with the ability to instance…

  • ADSP-21569 DDR3 Termination Resistor Value Required

    Hi

    1) What is the recommend type of  termination scheme and resistor value for address and command lines of ADSP-21569.

    In EE-418 document it is recommend to use series termination resistor of 100 ohms, but in Eval modules EV-21569-SOM & ADZS-21569-EZKIT…

  • RE: FIR Accelerator for adsp-21569

    I already looked at at it. It does not cover Downsampling and upsampling  FIR. Moreover, I do not have hardware to evaluate.

    I am interesting to know formula to estimate cycle cycle as it is provided in ADSP-2148x DSPs.

    Does it make sense to use formula…
