96 minor makefile update JonasDC 4125d 11h /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 4125d 11h /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 4138d 07h /mod_sim_exp/trunk/
92 updated documentation with minor interrupt changes of AXI interface JonasDC 4140d 12h /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 4142d 15h /mod_sim_exp/trunk/
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 4144d 06h /mod_sim_exp/trunk/
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4208d 04h /mod_sim_exp/trunk/
88 small update on documentation, changed fault in axi control_reg JonasDC 4214d 05h /mod_sim_exp/trunk/
87 updated documentation to version 1.4
core now supports the AXI4-Lite bus		 JonasDC 4214d 05h /mod_sim_exp/trunk/
86 update on previous JonasDC 4214d 05h /mod_sim_exp/trunk/
85 changed so that reset now also affects slave register JonasDC 4214d 05h /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 4215d 14h /mod_sim_exp/trunk/
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4217d 15h /mod_sim_exp/trunk/
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4234d 11h /mod_sim_exp/trunk/
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4234d 11h /mod_sim_exp/trunk/
78 updated documentation with new RAM style information JonasDC 4244d 05h /mod_sim_exp/trunk/
77 found fault in code, now synthesizes normally JonasDC 4250d 02h /mod_sim_exp/trunk/
76 testbench update JonasDC 4252d 13h /mod_sim_exp/trunk/
75 made rw_address a vector of a fixed width JonasDC 4252d 13h /mod_sim_exp/trunk/
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 4255d 09h /mod_sim_exp/trunk/
