2020-01-21Update DSP wrapper instance names.Pavel V. Shatov (Meister)
2019-10-23Added missing copyright headers.Pavel V. Shatov (Meister)
2019-10-21Reworked testbench, clk_sys and clk_core can now have any ratio, notPavel V. Shatov (Meister)
necessarily 1:2. Fixed compile-time issue where ISE fails to place two DSP slices next to each other, if A and/or B cascade path(s) between then are partially connected. Basically, if cascade is used, entire bus must be connected.
2019-10-21Further work:Pavel V. Shatov (Meister)
- added core wrapper - fixed module resets across entire core (all the resets are now consistently active-low) - continued refactoring
2019-10-21Redesigned the testbench. Core clock does not necessarily need to be twicePavel V. Shatov (Meister)
faster than the bus clock now. It can be the same, or say four times faster.
2019-10-03Added 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.
2019-10-01Redesigned core architecture, unified bank structure. All storage blocks nowPavel V. Shatov (Meister)
have eight 4kbit entries and occupy one 36K BRAM tile.
2019-10-01Major rewrite (different core hierarchy, buses, wrappers, etc).Pavel V. Shatov (Meister)
