	specifically working on 32-bit operands. HEADSUP: This breaks builds that use the old file names.
2015-06-23	Updated 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.

	block memory.

2015-06-23	Adding module parameters for generic operand size to modexp_core and top ↵	Joachim Strömbergson

2015-06-23	Updated residue module to use generic operand size.	Joachim Strömbergson

2015-06-23	Made the adder and shifters words size generic. Updated the montprod and ↵	Joachim Strömbergson
	residue to use the generic adder and shifters.
2015-06-22	Changed blockmem1r1w used in montprod to generic data and address widths. ↵	Joachim Strömbergson
	Updated instantiation to use generics.
2015-06-22	Adding a minor comment in the header to exmplain what the module parameters ↵	Joachim Strömbergson
	means.
2015-06-22	Changing module interface and internal defines to use symbolic widths for ↵	Joachim Strömbergson
	operand data size and addresses. We need to update counters too.
2015-06-22	Consolidated address settings, removed stale s logic mux control, removed ↵	Joachim Strömbergson
	extra lsw set.

2015-06-22	Adding write control of s_mem for first iteration and adding a new stage in ↵	Joachim Strömbergson
	priority mux.
2015-06-22	Adding mux to allow integrating s_mem init with main adder loop.	Joachim Strömbergson

2015-06-18	Adding iteration flag to be used to remove zero fill of s_mem.	Joachim Strömbergson

2015-06-18	Update 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.
2015-06-17	Fixed order of states.	Joachim Strömbergson
