The test code:
kernel void cosin_testcase(float x<>, out float y<>)
{
y=cos(x);
}
int main()
{
int length=4;
float * x, *y;
int i=0;
x=(float*) malloc(sizeof(float) *length);
y=(float*) malloc(sizeof(float) *length);
for(i=0;i<length;i++){
x [ i ]=1611.625f;
y [ i ]=0.0f;
}
{
float x_stream<length>;
float y_stream<length>;
x_stream.read(x);
cosin_testcase(x_stream, y_stream);
y_stream.write(y);
}
for(i=0;i<length;i++){
printf("%lf\n",y [ i ] );
}
free(x);
free(y);
return 0;
}
