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 3920d 11h /
97 changes in makefile, and fifo's are now also in mod_sim_exp library JonasDC 3937d 04h /
96 minor makefile update JonasDC 3938d 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 3938d 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 3951d 01h /
93 Tag for Version 1.4 of The Modular Simulataneous Exponentiation Core. This version adds support for the AXI4-Lite bus interface. JonasDC 3953d 06h /
92 updated documentation with minor interrupt changes of AXI interface JonasDC 3953d 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 3955d 09h /
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 3957d 00h /
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4020d 22h /
88 small update on documentation, changed fault in axi control_reg JonasDC 4026d 23h /
87 updated documentation to version 1.4
core now supports the AXI4-Lite bus
JonasDC 4026d 23h /
86 update on previous JonasDC 4026d 23h /
85 changed so that reset now also affects slave register JonasDC 4027d 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 4028d 08h /
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4030d 09h /
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4047d 05h /
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4047d 05h /
80 renamed to version 1.1 to follow the versioning system JonasDC 4056d 23h /
79 Tag for version 1.3 (with new ram style JonasDC 4056d 23h /
78 updated documentation with new RAM style information JonasDC 4056d 23h /
77 found fault in code, now synthesizes normally JonasDC 4062d 20h /
76 testbench update JonasDC 4065d 07h /
75 made rw_address a vector of a fixed width JonasDC 4065d 07h /
74 removed C_NR_OP and C_NR_M from the generic of mod_sim_exp_core and made them contstants, because currently no other values than 4 an 2 resp. are supported/can be implemented. JonasDC 4068d 03h /
73 updated plb interface, mem_style and device generics added JonasDC 4069d 03h /
72 deleted old resources JonasDC 4070d 03h /
71 added synthesis report for altera and xilinx for the new ram.
added coregen sources for xilinx for primitive RAM
JonasDC 4070d 03h /
70 updated testbench for use with new core parameters
updated makefile, added new sources
JonasDC 4070d 03h /
69 big update, the mod_sim_exp core now has a selectable ram structure. a generic ram that should be usable in any fpga, a asymmetric ram that is usable for some devices of altera or xilinx and uses less resources. JonasDC 4070d 03h /
