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
