    Yes, 256M of SDRAM space is enough, but more than two 16-bit EMIF interface are asked for FPGA and FLASH Another question is confused me : as you say , the 6745/6743 include 16-bit interface ,Are the 32-bit instruction can run in a 16-bit width SDRAM ? the 32-bit variable can be accessed or storaged...

    Hollis Ambrose
    First let me preface my remarks by saying that I am fairly new to the C6727 and PADK board. What we want to do is to grab an A/D sample at a 1kHz rate, operate on that sample and then output to three D/A's. We are using CCS v4 and have imported several of Lyrtech's v3.3 projects in. Our...

  • Forum Post: [C672x] Can dMAX be used for a SPI Master Mode transfer, if so how?

    Paul45899
    Need to run a SPI port in Master Mode and use dMAX also. Documentation only talks about using dMAX for SPI slave mode. If I set up a SPI slave transfer in dMAX for a SPI in master mode and manually start the first transfer, will the SPI generate the proper input events to cause the slave transfer...

    Craig Leeds
    Gagan, I have working CSL dMAX code for the c6727B that currently uses a low-priority general-purpose 1-dimensional transfer from SDRAM to SDRAM. However, it does not run fast enough. So I want to convert it to a 1DN Burst dMAX operation. But I can't seem to be able to successfully trigger the...

    Basically what I'd like to do is to create an interrupt using the RTI timer. Details follow. I'd like to, if I can, count how many McASP receive operations have happened and interrupt the CPU when the count gets to a certain number.

  • Forum Post: SP Float to Int, rounding behavior

    Steven Tuttle
    In the C67x+ chips, the SPINT rounding behavior is controlled via rounding mode bits in the FPADCR register. Are these bits changed from the power-on defaults by any of the optimized DSP and/or math function libraries? Are there any TI supplied libraries that change these rounding bits from...

    FeiHong, If you look up the Errata sheet for the C6727B DSP chip, find the note "Advisory 1.2.2" in section 2. It state that the SPI Master boot mode on silicon revision 1.2 does not work. The Errata sheet is sprz232f.pdf. Steve

  • Forum Post: Re: Big interrupt latency for C6727 when performing memcpy

    Steven Tuttle
    Boll, Memcpy() is most likely masking/restoring interrupts before/after an optimized loop that copies data in memory. The compiler has to mask interrupts to avoid breaking assumptions the code generator/optimizer makes about the state of the instruction pipeline. Many other DSP and/or math library...
