hey,
I'm working on the implementation of an image compressor on an Fpga
and the problem I met is on the dct results
except the dc coefficient (average value of the others), all the other
coefficients are greatly different from the software method ( using
Matlab)
could anyone tell me how can I solve this problem or even explain it if it
is normal

Are you using fixed point or floating point arithmetic for your hardware implementation? -----Original Message----- From: cores-bounces at opencores.org [mailto:cores-bounces at opencores.org] On Behalf Of Massinissa82 at hotmail.com Sent: Monday, July 25, 2005 12:30 PM To: cores at opencores.org Subject: [oc] comparaison between hardware and software results of the DCT hey, I'm working on the implementation of an image compressor on an Fpga and the problem I met is on the dct results except the dc coefficient (average value of the others), all the other coefficients are greatly different from the software method ( using Matlab) could anyone tell me how can I solve this problem or even explain it if it is normal _______________________________________________ http://www.opencores.org/mailman/listinfo/cores
