From 62495c597ca8b60f733682661afdad9e0d3e0e2d Mon Sep 17 00:00:00 2001 From: Paul Selkirk Date: Mon, 16 Mar 2020 13:58:08 -0400 Subject: Increase NUM_MULTS to 32. This required finding and fixing every function that had a baked-in assumption that NUM_MULTS=8. --- rtl/modexpng_mmm_dual.v | 30 +++-------------- rtl/modexpng_parameters_x8.vh | 2 +- rtl/modexpng_recombinator_block.v | 68 +++++++-------------------------------- 3 files changed, 17 insertions(+), 83 deletions(-) (limited to 'rtl') diff --git a/rtl/modexpng_mmm_dual.v b/rtl/modexpng_mmm_dual.v index 9346a42..fd39943 100644 --- a/rtl/modexpng_mmm_dual.v +++ b/rtl/modexpng_mmm_dual.v @@ -829,18 +829,8 @@ module modexpng_mmm_dual input [NUM_MULTS_HALF_AUX-1:0] col_index_value;
