[PD] convolution code error

[Yves Degoyon]

hi,

i think the error is to harcode the size of arrays to 255.

in fact, arrays in1 and in2 are of the size of the n variable
passed to the perform routine and this variable is 64 by default
( the default block size ).


for(set=0; set<n; set++)


cheers,
