Intel HLS example reports

Dear Anand,

thanks for your reply....sorry for the confusion and messing things up....I have posted three codes below under headings SOURCE file, HEADER and TEST BENCH. This will definitely give you the whole idea.

Regarding your question ".What for the below lines are used and where is the function? " please check the third code under TEST BENCH.

Regarding your question "How check results session of code works?" also please check the third code under TEST BENCH.

SOURCE file

# include "../src/diff_sq_acc.h"

void diff_sq_acc(din_t a[N], din_t b[N], dout_t *dout)

{

unsigned char i;

float acc= 0;

float a_reg, b_reg, sub, sub2;

diff_sq_acc_label0:for(i=0; i<N; i++)

{

a_reg = a;

b_reg = b;

sub = a_reg - b_reg;

sub2 = sub*sub;

acc += sub2;

}

*dout = acc;

}
