user/shatov/modexpng - "Next-generation" modular exponentiation using the specialized DSP slices present in the Artix-7 FPGA

Age	Commit message (Collapse)	Author
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	Further work:	Pavel V. Shatov (Meister)
	- added core wrapper - fixed module resets across entire core (all the resets are now consistently active-low) - continued refactoring
2019-10-03	Reworked storage architecture (moved I/O memory to a separate module, since ↵	Pavel V. Shatov (Meister)
	there's only one instance of input/output values, while storage manager has dual storage space for P and Q multipliers). Started working on microcoded layer, added input operation and modular multiplication.
2019-10-03	Redesigned storage modules, added top-level module, added I/O storage space.	Pavel V. Shatov (Meister)

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)

2019-10-01	Started working on the pipelined Montgomery modular multiplier. Currently can	Pavel V. Shatov (Meister)
	do the "square" part of the multiplication, i.e. compute the twice larger intermediate product AB = A * B.
