    Looking for DSP chips to act as audio digital filter/interpolators and
    accept I2S standard as used in CD and DVD applications.

    Can anyone suggest some?

    thank you,

    Most modern DSPs have I2S interfaces. There are many different reasons to
    choose a particular DSP. The most popular family of DSPs in professional
    audio and high performance audio today are Analog Devices' SHARC devices.
    We manufacture many different boards using SHARC DSPs. We also have several
    different I/O modules with I2S based audio converters.
  4. What's the raw MIPS (FLOPS?) of top end SHARC DSPs?

    The ADSP-21262 uses a core clock of 200 MHz but can operate in SIMD mode.
    This means that you can fetch data and modify the pointers for the next
    time fetch, multiply two sets of fixed or floating point numbers, and add
    these numbers in a single cycle.

    The ADSP-21364 is similar at 333 MHz. ADI claims 2GFLOPs for this part
    based on all the parallelism.

    The upcoming ADSP-21369 will operate up to 400 MHz.
  6. That sounds rather tempting.
    What sort of prices 100up?

    $20+ in hundreds depending on the part. There is also a lower cost ADSP-

    We have a price list on our website for our boards. We also resell Analog
    Devices Visual DSP, Emulators and EZ-Kits.

    Are there online instructions on how to program the AD chips?
    How about TI DSP chips?
