Rev Log message Author Age Path
97 changes in makefile, and fifo's are now also in mod_sim_exp library JonasDC 3976d 20h /mod_sim_exp/trunk/
96 minor makefile update JonasDC 3977d 20h /mod_sim_exp/trunk/
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 3977d 21h /mod_sim_exp/trunk/
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 3990d 17h /mod_sim_exp/trunk/
92 updated documentation with minor interrupt changes of AXI interface JonasDC 3992d 22h /mod_sim_exp/trunk/
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 3995d 01h /mod_sim_exp/trunk/
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 3996d 15h /mod_sim_exp/trunk/
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4060d 14h /mod_sim_exp/trunk/
88 small update on documentation, changed fault in axi control_reg JonasDC 4066d 15h /mod_sim_exp/trunk/
87 updated documentation to version 1.4
core now supports the AXI4-Lite bus		 JonasDC 4066d 15h /mod_sim_exp/trunk/
86 update on previous JonasDC 4066d 15h /mod_sim_exp/trunk/
85 changed so that reset now also affects slave register JonasDC 4066d 15h /mod_sim_exp/trunk/
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 4068d 00h /mod_sim_exp/trunk/
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4070d 01h /mod_sim_exp/trunk/
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4086d 21h /mod_sim_exp/trunk/
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4086d 21h /mod_sim_exp/trunk/
78 updated documentation with new RAM style information JonasDC 4096d 15h /mod_sim_exp/trunk/
77 found fault in code, now synthesizes normally JonasDC 4102d 12h /mod_sim_exp/trunk/
76 testbench update JonasDC 4104d 23h /mod_sim_exp/trunk/
75 made rw_address a vector of a fixed width JonasDC 4104d 23h /mod_sim_exp/trunk/
