在DM8148 cortex-A8端,ccs开发环境,想利用neon指令集,做算法优化,如何来完成



Hello 您好,

由于项目需求,想在DM8148 cortex-A8端,利用ccs开发环境,arm的neon指令集,做算法优化,如何来完成环境的搭建,

包括neon/VFP 功能的使能(我看网上有说,要用汇编代码使能其)?

我自己建了一个工程,调用了#include "arm_neon.h"

但是ccs无法找到该头文件,我从别的地方arm DS-5 环境下copy了 "arm_neon.h" 头文件,但是CCS有无法找到,其中的定义,

如下:

"..\arm_neon.h", line 40: error #20: identifier "__simd64_int8_t" is undefined
"..\arm_neon.h", line 41: error #20: identifier "__simd64_int16_t" is undefined
"..\arm_neon.h", line 42: error #20: identifier "__simd64_int32_t" is undefined
"..\arm_neon.h", line 43: error #20: identifier "__builtin_neon_di" is undefined

不知道ccs环境下,如何创建完成这个环境的搭建,

如果方便的话,最好有例程,非常感谢!

BRS,
