SortRadix
向量基数排序，包含升序和降序。
- 辅助函数：
HmppResult HMPPS_SortRadixInit(int32_t len, HmppDataType dataType, uint8_t **buffer);
HmppResult HMPPS_SortRadixRelease(uint8_t* buffer);
- 整型数的升序排序：
HmppResult HMPPS_SortRadixAscend_8u_I(uint8_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_16u_I(uint16_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_16s_I(int16_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_32u_I(uint32_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_32s_I(int32_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_64u_I(uint64_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_64s_I(int64_t *srcDst, int32_t len, uint8_t* buffer);
- 浮点数的升序排序：
HmppResult HMPPS_SortRadixAscend_32f_I(float *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixAscend_64f_I(double *srcDst, int32_t len, uint8_t* buffer);
- 整型数的降序排序：
HmppResult HMPPS_SortRadixDescend_8u_I(uint8_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_16u_I(uint16_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_16s_I(int16_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_32u_I(uint32_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_32s_I(int32_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_64u_I(uint64_t *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_64s_I(int64_t *srcDst, int32_t len, uint8_t* buffer);
- 浮点数的降序排序：
HmppResult HMPPS_SortRadixDescend_32f_I(float *srcDst, int32_t len, uint8_t* buffer);
HmppResult HMPPS_SortRadixDescend_64f_I(double *srcDst, int32_t len, uint8_t* buffer);

示例
#define BUFFER_SIZE_T 9
void Sort_Example() {
uint8_t src[BUFFER_SIZE_T] = {255, 0, 254, 0, 253, 1, 252, 2, 251};
int32_t i;
uint8_t *buffer;
HMPPS_SortRadixInit(BUFFER_SIZE_T, HMPP8U, &buffer);
HmppResult result = HMPPS_SortRadixAscend_8u_I(src, BUFFER_SIZE_T，buffer);
if (result == HMPP_STS_NO_ERR) {
printf("result = %d\n", result);
printf("dst = ");
for (i = 0; i < BUFFER_SIZE_T; i++) {
printf("%d ", src[i]);
}
printf("\n");
}
HMPPS_SortRadixRelease(buffer);
}
运行结果：
result = 0 dst = 0 0 1 2 251 252 253 254 255
