When I used C2H to accelerate my code,I met some problems.
I chose a fuction to accelerate,but the report told me that:"The code does not contain any loop...".But it has 6 loops.
I don't know what's wrong.Please help me.Thank you!
-------------------------------------My code below-------------------------------------------
void HistogramEql(alt_16 nWidth, alt_16 nHeight, alt_u8 *lpInput, alt_u8 *lpOutput)
{
alt_16 x, y;
# define Point1(x, y) lpInput[(x) + (y) * nWidth]
# define Point(x, y) lpOutput[(x) + (y) * nWidth]
alt_16 r[256], s[256];
alt_16 i;
i=0;
do{
r
=s=0;
i++;
}while(i<256);
for (y = 0; y < nHeight; y++)
{
for (x = 0; x < nWidth; x++)
{
r[Point1(x, y)]++;
}
}
s[0] = r[0];
for (y = 1; y < 256; y++)
{
s[y] = s[y - 1];
s[y] += r[y];
}
for (y = 0; y < nHeight; y++)
{
for (x = 0; x < nWidth; x++)
{
Point(x, y) = s[Point1(x, y)] * 255 / nWidth / nHeight;
}
}
}
