2015-06-24Fused the s_mem init loop into the adder loop.Joachim Strömbergson
2015-06-24Small improvement in report of test result.Joachim Strömbergson
2015-06-24Reorganized address generation and bit index generation.Joachim Strömbergson
2015-06-24Corrected suffixes and cleaned up product address generation.Joachim Strömbergson
2015-06-24(1) Untangled the word index address generator from the product logic. (2) ↵Joachim Strömbergson
Updated the montprod TB to match changed FSM states in montprod.
2015-06-23Fixed incorrect compile time expression for sizing the memory.Joachim Strömbergson
2015-06-23Changed name of files to reflect that the adder and the shifters are now not ↵Joachim Strömbergson
specifically working on 32-bit operands. HEADSUP: This breaks builds that use the old file names.
2015-06-23Updated all modules below modexp_core has been updated to have generic ↵Joachim Strömbergson
operand size. Updated module integrations in modexp_core to set the operand width and address width.
2015-06-23Updated the 2r1w block memory to be operand size generic. Minor fix in 1r1w ↵Joachim Strömbergson
block memory.
2015-06-23montprod now supports generic operand size.Joachim Strömbergson
2015-06-23Adding module parameters for generic operand size to modexp_core and top ↵Joachim Strömbergson
level localparams with explanation in modexp.v to control the core instantiation.
2015-06-23Updated residue module to use generic operand size.Joachim Strömbergson
2015-06-23Made the adder and shifters words size generic. Updated the montprod and ↵Joachim Strömbergson
residue to use the generic adder and shifters.
2015-06-22Changed blockmem1r1w used in montprod to generic data and address widths. ↵Joachim Strömbergson
Updated instantiation to use generics.
2015-06-22Adding a minor comment in the header to exmplain what the module parameters ↵Joachim Strömbergson
means.
2015-06-22Changing module interface and internal defines to use symbolic widths for ↵Joachim Strömbergson
operand data size and addresses. We need to update counters too.
2015-06-22Consolidated address settings, removed stale s logic mux control, removed ↵Joachim Strömbergson
extra lsw set.
2015-06-22Killed off debug in RTL since we now whow info from TB.Joachim Strömbergson
2015-06-22Removing stale states in FSM.Joachim Strömbergson
2015-06-22Removing state that has been collapsed.Joachim Strömbergson
2015-06-22Cleanup of prodcalc.Joachim Strömbergson
2015-06-22Adding write control of s_mem for first iteration and adding a new stage in ↵Joachim Strömbergson
priority mux.
2015-06-22Adding mux to allow integrating s_mem init with main adder loop.Joachim Strömbergson
2015-06-18Adding iteration flag to be used to remove zero fill of s_mem.Joachim Strömbergson
2015-06-18Moved s logic mux control to control fsm.Joachim Strömbergson
2015-06-18Correct update after linting.Joachim Strömbergson
2015-06-18Restored version of montprod to a version that actually works.Joachim Strömbergson
2015-06-18Combined case statements to make it easier to follow the sequences.Joachim Strömbergson
2015-06-18Update after linting after cycle collapsing.Joachim Strömbergson
2015-06-17(1) Collapsed the sm and sa adder states. Thisimoproves performance for ↵Joachim Strömbergson
modexp with 3%. (2) Updated montprod testbench to not use the now removed states. (3) Minor code cleanup to make it easier to work with for further improvements.
2015-06-17(1) Cleaned up bit select for operand b and a. (2) Fixed name of loop ↵Joachim Strömbergson
counter. (3) Reordered processes to main datapath first.
2015-06-17Fixed order of states.Joachim Strömbergson
2015-06-16Merge of s_mux and s_write to allow cycle collapsing.Joachim Strömbergson
2015-06-16Fixed final big testcase to match python model.Joachim Strömbergson
2015-06-16Collapsing cycles for loop counter. Updating testbench to match removed cycles.Joachim Strömbergson
2015-06-16Collapsed done. Removes one cycle from each montprod.Joachim Strömbergson
2015-06-16Fixed non trivial yet fairly short testcases.Joachim Strömbergson
