| 2019-10-03 | Added more micro-operations, entire Montgomery exponentiation ladder works now. | Pavel V. Shatov (Meister) | |
| 2019-10-03 | Added more micro-operations, also added "general worker" module. The worker ↵ | Pavel V. Shatov (Meister) | |
| is basically a block memory data mover, but it can also do some supporting operations required for the Garner's formula part of the exponentiation. | |||
| 2019-10-03 | Expanded micro-operation parameters (added dedicated control bit to force ↵ | Pavel V. Shatov (Meister) | |
| the B input of the modular multiplier to 1, this is necessary to bring numbers out of Montgomery domain). | |||
| 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 | Implemented the final stage of the Montgomery modular multiplication, i.e. | Pavel V. Shatov (Meister) | |
| addition of AB and M then reduction by right-shift. | |||
| 2019-10-01 | Further work on the Montgomery modular multiplier. Added the third | Pavel V. Shatov (Meister) | |
| "rectangular" stage of the multiplication process, i.e. computation of how many copies of the modulus N to add to the intermediate product AB to zeroize the lower half: M = Q * N. | |||
| 2019-10-01 | Further work on the Montgomery modular multiplier. Can now to the "triangular" | Pavel V. Shatov (Meister) | |
| part of multiplication, i.e. compute the "magic" reduction coefficient Q = LSB(AB) * N_COEFF. | |||
| 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. | |||
