2020-02-11	More elegant way to do partial product recombination:	Pavel V. Shatov (Meister)
	* take advantage of the cascade paths between DSP slices * decrease latency of operation
2020-02-03	New partial product recombination algorithm.	Pavel V. Shatov (Meister)

2020-01-30	This commit accomodates the changes made to DSP slice wrappers and also fixes	Pavel V. Shatov (Meister)
	the subtle math overflow bug introduced while switching to DSP-based partial multiplication product recombination.
2020-01-21	Refactored MMM recombinator module, accomodated the changes in DSP slice	Pavel V. Shatov (Meister)
	wrapper names.
2019-10-23	Added missing copyright headers.	Pavel V. Shatov (Meister)

2019-10-21	Entire CRT signature algorithm works by now.	Pavel V. Shatov (Meister)
	Moved micro-operations handler into a separate module file, this way we don't have any synthesized stuff in the top-level module, just instantiations. This is more consistent from the design partitioning point of view. Btw, Xilinx claims their tools work better that way too, but who knows... Added optional simulation-only code to assist debugging. Un-comment the ENABLE_DEBUG `define in 'rtl/modexpng_parameters.vh' to use, but don't ever try to synthesize the core with debugging enabled.
2019-10-01	Redesigned core architecture, unified bank structure. All storage blocks now	Pavel V. Shatov (Meister)
	have eight 4kbit entries and occupy one 36K BRAM tile.
2019-10-01	Major rewrite (different core hierarchy, buses, wrappers, etc).	Pavel V. Shatov (Meister)
