Rev Log message Author Age Path
97 changes in makefile, and fifo's are now also in mod_sim_exp library JonasDC 3993d 18h /mod_sim_exp/trunk/
96 minor makefile update JonasDC 3994d 18h /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 3994d 18h /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 4007d 14h /mod_sim_exp/trunk/
92 updated documentation with minor interrupt changes of AXI interface JonasDC 4009d 19h /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 4011d 22h /mod_sim_exp/trunk/
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 4013d 13h /mod_sim_exp/trunk/
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4077d 11h /mod_sim_exp/trunk/
88 small update on documentation, changed fault in axi control_reg JonasDC 4083d 12h /mod_sim_exp/trunk/
87 updated documentation to version 1.4
core now supports the AXI4-Lite bus
JonasDC 4083d 12h /mod_sim_exp/trunk/
86 update on previous JonasDC 4083d 13h /mod_sim_exp/trunk/
85 changed so that reset now also affects slave register JonasDC 4083d 13h /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 4084d 21h /mod_sim_exp/trunk/
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4086d 22h /mod_sim_exp/trunk/
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4103d 18h /mod_sim_exp/trunk/
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4103d 18h /mod_sim_exp/trunk/
78 updated documentation with new RAM style information JonasDC 4113d 12h /mod_sim_exp/trunk/
77 found fault in code, now synthesizes normally JonasDC 4119d 09h /mod_sim_exp/trunk/
76 testbench update JonasDC 4121d 20h /mod_sim_exp/trunk/
75 made rw_address a vector of a fixed width JonasDC 4121d 20h /mod_sim_exp/trunk/
