替换库文件

我的函数没有定义~不过没看懂load函数干什么的
后来把load.asm添加以后就好了
附_load.sam

      .global _load

      .text

N    .set 1000

;
;  ======== _load ========
;  This function simulates a load on the DSP by executing N * loopCount
;  instructions, where loopCount is the input parameter to load().
;
;    void _load(int loopCount)
;
;  The loop is using 8 instructions. One instruction for sub, nop and
;  b, plus nop 5. The extra nop added after sub is to make the number
;  of instructions in the loop a power of 2.
;
_load:

      mv a4, b0             ; use b0 as loop counter
  [!b0] b lend
      mvk N,b1
      mpy b1,b0,b0
      nop
      shru b0,3,b0          ; (loop counter)= (# loops)/8

loop:
      sub b0,1,b0 本帖最后由 dontium 于 2015-1-23 11:13 编辑
