    Hi,Andy:

        硬件：66AK2H12

        软件：CCS6.1

        DSP系统：BIOS

         ARM系统：SMP-LINUX

        TI针对他们的DSP程序优化，可以做线性汇编优化或并行汇编优化，CCS中可以设置一些参数，比如产生.asm文件来帮助开发者更好的设计汇编代码，从而达到算法的深度优化。

        我想请教你的问题就是：

        在66AK2H12的ARM端开发中，假如我想做算法的汇编优化

        Q1：CCS有没有提供类似的一些机制来帮助开发者完成ARM汇编的深度优化？

        Q2：TI有没有提供ARM汇编优化的参考代码？比如H264的ARM编解码汇编代码


        谢谢！！！

      

          Best Regards

               Gavin

    对于初学者，要学习keyStone2，是否需要EVM板？或如何学习keyStone2? 请各位给些建议，谢谢！

    您好，谢谢您分享的例程。我的开发板买了很久都不知道怎么学，我用您的例程跑了第一个程序Timer，在此，有几个问题想问您：

    我用的是EVMK2E开发板，芯片是c66ak2e05.

    1、我的程序运行之后和文档里的结果不一致，具体如下，请问是我哪出问题了，为什么所有的counter都是0 ？

    [C66xx_0] Initialize DSP main clock = 122.88MHz/4x39 = 1198MHz

    Enable Exception handling...
    a pulse will be generated on TIMO0...
    a pulse was generated on TIMO0
    clocks will be generated on TIMO0...
    clocks were generated on TIMO0
    start watch-dog timer...
    service watch-dog 1 times, at time counter = 0
    service watch-dog 2 times, at time counter = 0
    service watch-dog 3 times, at time counter = 0
    service watch-dog 4 times, at time counter = 0
    service watch-dog 5 times, at time counter = 0
    service watch-dog 6 times, at time counter = 0
    service watch-dog 7 times, at time counter = 0
    service watch-dog 8 times, at time counter = 0
    service watch-dog 9 times, at time counter = 0
    service watch-dog 10 times, at time counter = 0
    service watch-dog 11 times, at time counter = 0
    service watch-dog 12 times, at time counter = 0
    service watch-dog 13 times, at time counter = 0
    service watch-dog 14 times, at time counter = 0
    service watch-dog 15 times, at time counter = 0
    service watch-dog 16 times, at time counter = 0
    service watch-dog 17 times, at time counter = 0
    service watch-dog 18 times, at time counter = 0
    service watch-dog 19 times, at time counter = 0
    service watch-dog 20 times, at time counter = 0
    service watch-dog 21 times, at time counter = 0
    service watch-dog 22 times, at time counter = 0
    service watch-dog 23 times, at time counter = 0
    service watch-dog 24 times, at time counter = 0
    service watch-dog 25 times, at time counter = 0
    service watch-dog 26 times, at time counter = 0
    service watch-dog 27 times, at time counter = 0
    service watch-dog 28 times, at time counter = 0
    service watch-dog 29 times, at time counter = 0
    service watch-dog 30 times, at time counter = 0
    stop servicing watch-dog, it will timeout and trigger NMI...

    2、还有，就是我load .out 文件后，提示发生异常，是怎么回事呢？

    Initialize DSP main clock = 122.88MHz/4x39 = 1198MHz

    External exception happened. MEXPFLAG[3]=0x20000000.

    Exception happened at a place can not safely return!
    3、我是个菜鸟，如果方便的话，可不可以加您的qq或者邮箱，方便沟通问题。
