Thanks for replies. By "results" I mean resource utilisation and timing analysis results.
I have a FIR filter with a chain of 8 MAC modules:
--- Quote Start ---
mac0 : mac
port map ( aclr0 => mac_rst,
clock0 => clk,
dataa => sample(0),
datab => coeff(0),
overflow => of(0),
result => sum(0)
);.
.
.
mac7 : mac
port map ( aclr0 => mac_rst,
clock0 => clk,
dataa => sample(7),
datab => coeff(7),
overflow => of(7),
result => sum(7)
);
--- Quote End ---
Sample, coeff and sum are arrays of vectors.
Instead, I wrote it like this:
--- Quote Start ---
mac_components : for i in 0 to 7 generate
begin macs : component mac
port map(mac_rst, clk, sample(i), coeff(i), of(i), sum(i));
[/INDENT]end generate mac_components;
--- Quote End ---
I'm not sure about this change because, according to TQ, timing results are a bit worse (but still within margin).
Should I be so careful with this type of code?
