a[3]={15,25,24}
b[3]={12,32,13}
求c[i]=| a[i]-b[i] |，用C来调用线性汇编？谢谢
第二个问题：SUBABS4这个指令如何结合数组使用？谢谢？
我觉得没必要写线性汇编，用TI的intrinsic写C代码就能达到和汇编一样的效率。关于C6000优化你可以参考一下： http://www.deyisupport.com/question_answer/dsp_arm/c6000_multicore/f/53/t/19044.aspx
SUBABS4操作的是16比特整数，如果你的数据类型也是16比特整数，那么用intrinsic写成这样
for( i = 0; i< length; i+=4 ){ a0123 = _amem8(&ptr_a[i]); b0123 = _amem8(&ptr_b[i]); _amem8(&ptr_c[i]) = _subabs4(a_9123,b_0123);}
还是不会
希望您能给我完整的程序
