• RE: compress and decompress in VisualDSP++

    Hi,

    From the tools perspective, the Loader supports compression using the ZLib compression engine for some of the older Blackfin processors (BF53x), with example decompression DXEs and further information available in the VisualDSP++ installation under…

  • Does the BF537 really have 3 16-bit MACs?

    According to the datasheet for the BF537/BF534/BF536 each chip is able to support three 16-bit MACs, but the Analog Devices spreadsheet comparison tool states:

    BF534     500MHz     1000MMACS

    BF536     400MHz     800MMACS

    In fact, the details for the BF537 are all…

  • BF534 spurious stack overflow.

    Hi,

    We are having problems with a BF534 running a VDK-based C++ application. Basically, at (fairly rare) random intervals it crashes, locking up with a stack overflow. The system stack is currently 16k, and I have tried both 8k and 32k, and the frequency…

  • RE: BF534 Clock Buffer

    Hi Brian,

    The buffered version of CLKIN signal appears on CLKBUF pin of processor. It does not come from any PLL. So, I am not sure what information you are looking for. Below is the dia from datasheet which explains this:

    The signal on CLKOUT comes…

  • RE: BF534 sdram expansion

    Hi,

    I think the BF534 processor support a maximum of 128M Byte of SDRAM.

    If this is sufficient for the customer then they can go for two MT48LC64M8A2( which is 64 MB ) chips making up the total external memory of 128MB. In this configuration one of…

  • regarding AN-813: Interfacing the ADSP Blackfin Processors to High Speed Parallel ADCs

    I really want to know:

    one page 1, figure 1, PPI0_FS1, PPI0_CLK, for following Blackfin processors, do I need external LOGIC?

    BF538, BF542, BF547, BF548

    This figure is confusing: it said BF534/6/7 but said BF534/5/6 in two difference places? what a…

  • RE: Question about silicon revision

    Hi Lloyd,

    I have tryed this, but I am using SPI boot method. Apparently the lower silicon revisions doesn´t support boot via SPI.

    Sorry I have forgot to mention that.

    The compilation will fail as follow:

    I should add that I am developing for the BF534 on a custom board.

  • BF534 timer in WIDTH CAPTURE mode

      Hi,

      I'm using a BF534 with VDSP++ 5.0(update 7) and the SSL to  control a timer to try to capture the width

    of a single, one off pulse.

      I've programmed the timer with:

    static const ADI_TMR_GP_CMD_VALUE_PAIR   ambient_data[] = {
