101 added README file for simulation, minor update for Makefile clean target. JonasDC 4140d 04h /
100 added version 1.0 tag for completeness. This version is the first version that is adapted to the opencores design rules. Also the code is cleaned up. previous tag was incorrect, now updated JonasDC 4158d 11h /
99 removed tag, wrong directory tagged JonasDC 4158d 12h /
98 added version 1.0 tag for completeness. This version is the first version that is adapted to the opencores design rules. Also the code is cleaned up. JonasDC 4158d 12h /
97 changes in makefile, and fifo's are now also in mod_sim_exp library JonasDC 4175d 05h /
96 minor makefile update JonasDC 4176d 05h /
95 new control logic for the core, allow for greater frequencies for the multiplier.
changes:
- autorun_cntrl: the bit selection for the exponents is now implemented with a shift register in stead of a mux. credits to Geoffrey Ottoy for new design structure.
- mont_cntrl: gave the databus from and to the RAM more time to settle. data now has 3 clocks to get to its destination.		 JonasDC 4176d 05h /
94 BIG update: core now supports different clock speed for the multiplier core, so more performance is posible. currently this version is working in simulation and is being tested on hardware. Changes in this update include:
- changed RAM and memory to support different clocks
- new FIFO that supports dual clock (slightly modified version of generic_fifo's on OpenCores.org)
- parameter C_FIFO_DEPTH is now replace by C_FIFO_AW (address width of the fifo pointers)
- added logic for control signals to cross from one clock domain to another
- updated testbenches and interfaces accordingly
- added log of synthesis of the 2 new fifo's for Xilinx		 JonasDC 4189d 01h /
93 Tag for Version 1.4 of The Modular Simulataneous Exponentiation Core. This version adds support for the AXI4-Lite bus interface. JonasDC 4191d 06h /
92 updated documentation with minor interrupt changes of AXI interface JonasDC 4191d 06h /
91 changed interrupt structure of AXI4-Lite interface. Now the interrupt has to be acknowledged by clearing the appropriate interrupt source flag in the control register. JonasDC 4193d 09h /
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 4195d 00h /
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4258d 22h /
88 small update on documentation, changed fault in axi control_reg JonasDC 4264d 23h /
87 updated documentation to version 1.4
core now supports the AXI4-Lite bus		 JonasDC 4265d 00h /
86 update on previous JonasDC 4265d 00h /
85 changed so that reset now also affects slave register JonasDC 4265d 00h /
84 AXI-Lite interface updated, now tested and verified on Xilinx FPGA
renamed C_DEVICE parameter, because of conflicts with restricted parameter in xilinx XPS		 JonasDC 4266d 08h /
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4268d 09h /
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4285d 05h /
