Intel HLS example reports

Dear Anand

While going through AC data types used by Intel HLS, I have written the same code in terms of ac_fixed data types below. I will be really grateful if you can run and synthesize at your end. Thanks in advance......you have been so far very helpful.....

void diff_sq_acc( ac_ufixed<11,1> a[N], ac_ufixed<11,1> b[N], ac_ufixed<28,8> *dout)

{

unsigned char i;

ac_ufixed<28,8> acc= 0;

ac_ufixed<11,1> a_reg, b_reg;

ac_fixed<12,2> sub;

ac_ufixed<21,1> sub2 ;

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

{

# pragma HLS PIPELINE II=1

a_reg = a;

b_reg = b;

sub = a_reg - b_reg;

sub2 = sub*sub;

acc += sub2;

}

*dout = acc;

}
