How about that we do this in two steps: (1) Increase the sys_clk for the cores to 100 MHz as discussed and decided on before. (2) Investigate and try and run the cores synchronously with the 90 MHz. The point I see by doing this is that if we do (1) and don't see major performance improvements, we should know a bit more about where the bottleneck is hiding. Doing (1) should also confirm that we can run the cores at 90 MHz with no problems. So it would be a bit of a pipe-clean for (2). (1) _should_be an easy thing to do. Lets not wait anymore. Pavel, I've asked a few times now, can you please confirm or correct the suggested changes to the sys_clk clock generator parameters? And is the changes to those parameters the only place we need to update. No changes in the ucf-file? - -- Med vänlig hälsning, Yours Joachim Strömbergson - Assured AB ======================================================================== -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBCAAGBQJbDQynAAoJEF3cfFQkIuyNYFUP+gJGTfRn0ld0V34mFH2f71Dz NuTpT2Q02lrXfP7F1/cSaSkWr1PGQvF4llF3BmwcFt7l61sVSPMogIdMd+H4/sU3 kHlYYK3T8fimLAF8UJWkVUD+8D5kIoNpvzY29VfM/QToF9o9FSx2MYTNH0wFmXpI Gyl8QBo35yKkBt+LI6GtmFshsF5LosDz+NNYBojl1p0wxkp5tkIau5pxTviVNYtu zNvcUOaiKmQzLRlbopdfQTJv5CPIuWWkcVCaZXUgjPyYAbtZnxarhh7vJ/wMtoE6 r5394dUw72IF8Qu5jT9c33RwjCPFbBst2t3Ggsm3OVHQIQtPQYb7wQFSDEOQYFvp uULOcQeNpVl7ItDkLKFyDYF6KKQKBx+brQO653/c1NXkaUxtTGZo2g9IKwTsWlt4 nJ5spbnfc2kq2rrQRXJj00/h6DIDW4C+4UU3Na/CoW2QLs99Aev+QnM2rFxaNveN bTixpsHka1cPNoyTiHHLSKB9B7/r4LrDBwLxevh3V1QSZ/5oWzL8ASo9QR63qCj1 txo1JQhPNGW6LQRGO+xkmwV+7gDG5483QtIglry9Dvu9OcMfmx87jXhiVjKm2tN7 0u4CQUOM5Y9ImVpq3iwRmhYCtitNzR2IkaWcfDHRcdANmXjdNwhZvaHAf4m4MzuT y6RxDCNVzj4VH2gS8T2O =3vvV -----END PGP SIGNATURE----- _______________________________________________ Tech mailing list Tech@cryptech.is https://lists.cryptech.is/listinfo/tech
