| 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. | |||
| 2019-10-01 | Moved to "modexpng_fpga_model" repo, this one was meant for Verilog. | Pavel V. Shatov (Meister) | |
| 2019-08-19 | * More cleanup (got rid of .wide. and .narrow.) | Pavel V. Shatov (Meister) | |
| * Working microcode for non-CRT exponentiation (i.e. when only d is known) | |||
| 2019-08-19 | * MASSIVE CLEANUP | Pavel V. Shatov (Meister) | |
| * All the data buses are now either 16 or 18 bits wide for consistency * More consistent naming of micro-operations * More debugging options (can specify which ladder iteration to dump) | |||
| 2019-08-19 | * Added more micro-operations | Pavel V. Shatov (Meister) | |
| * Working microcode for CRT exponentiation * Further refactoring | |||
| 2019-08-19 | * Started conversion of the model to use micro-operations | Pavel V. Shatov (Meister) | |
| * Added initial operand bank structure (working "wide"/"narrow" pairs plus input & output banks). The core has four pairs of working banks (X.X and X.Y for Montgomery ladder with modulus P, Y.X and Y.Y for modulus Q) | |||
| 2019-08-19 | * Added more debugging options: | Pavel V. Shatov (Meister) | |
| - intentionally trigger internal overflow handler - dump MAC inputs - dump intermediate numbers during the reduction phase * Bus widths changes * Some cosmetic changes | |||
| 2019-04-04 | Intermediate version to fix recombinaton overflow bug. | Pavel V. Shatov (Meister) | |
| 2019-04-04 | Fixed 4096-bit test vector generation. | Pavel V. Shatov (Meister) | |
| 2019-04-02 | Removed some boilerplate code, all the three multiplication flavours are now | Pavel V. Shatov (Meister) | |
| working consistently. Still need to rework recombination routines. | |||
| 2019-04-02 | Cosmetic fixes. | Pavel V. Shatov (Meister) | |
| 2019-04-02 | Same changes for "triangle" multiplication phase as for the "square" one | Pavel V. Shatov (Meister) | |
| (debugging output, simpler MAC clearing and index rotation logic). | |||
| 2019-04-02 | Rewrote "square" recombination to match how it works in hardware. | Pavel V. Shatov (Meister) | |
| 2019-03-30 | * more debugging output | Pavel V. Shatov (Meister) | |
| * more precise modelling of DSP slice | |||
| 2019-03-24 | Simplified index calculation and accumulator clearing logic. | Pavel V. Shatov (Meister) | |
| Better debug printout of accumulators. | |||
| 2019-03-23 | Added optional output of intermediate quantities for debugging. | Pavel V. Shatov (Meister) | |
| Reworked index rotation code for better readability. | |||
| 2019-03-23 | Mutate blinding tuple. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | Added blinding into math model. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | ModExpNG ("Next Generation") math model. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | Updated readme file. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | Added blinding support to test vector generation scripts. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | Instructions on how to use the vector generation scripts. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | Don't track the test vector itself. | Pavel V. Shatov (Meister) | |
| 2019-03-23 | Randomized test vector generation scripts for ModExpNG. | Pavel V. Shatov (Meister) | |
