> You can directly LLA filters + 16 * 8 * 2 and save one add. Same below.
You can

It

Okay, updated them
> Use a macro parameter for the stride register.
Doing this will reduce one if-else statement in this patch, but in the next
patch, it will lead to adding multiple if-else statements. I think we can
leave it unchanged.
