    Seems you should do ejtag chain test first. On Navigator Console, you could use jtagchain command.

    Shabeer,

    Yes, I saw a similar problem. Even I added “-ffixed-reg” options, the builtin functions still use other ac registers.

    But I don’t think this is same as your issue. I wrote some complex code which uses many builtin DSP functions before, I checked line by line, I think it is efficient enough.

    Shabeer,

    So what is the gcc version in your android tools?

    And O3 always do more aggressive optimization. Sometimes the result will surprise you.

    If you could show more code or a simple project, I think I could help.

    Hi Shabeer,

    Could you show how your dpaq_s_w_ph is implemented?

    There is a built-in function __builtin_mips_dpaq_s_w_ph for DPAQ_S.W.PH instruction.
