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

92 updated documentation with minor interrupt changes of AXI interface JonasDC 3942d 04h /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 3944d 07h /mod_sim_exp/trunk/
90 reverted changes from previous revision, updated AXI version with testbench JonasDC 3945d 22h /mod_sim_exp/trunk/
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4009d 20h /mod_sim_exp/trunk/
88 small update on documentation, changed fault in axi control_reg JonasDC 4015d 21h /mod_sim_exp/trunk/
87 updated documentation to version 1.4
core now supports the AXI4-Lite bus
JonasDC 4015d 22h /mod_sim_exp/trunk/
86 update on previous JonasDC 4015d 22h /mod_sim_exp/trunk/
85 changed so that reset now also affects slave register JonasDC 4015d 22h /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 4017d 06h /mod_sim_exp/trunk/
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4019d 07h /mod_sim_exp/trunk/
82 added first version of axi-lite interface and testbench for basic axi-lite operations, now under test JonasDC 4036d 03h /mod_sim_exp/trunk/
81 updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration JonasDC 4036d 03h /mod_sim_exp/trunk/
78 updated documentation with new RAM style information JonasDC 4045d 21h /mod_sim_exp/trunk/
77 found fault in code, now synthesizes normally JonasDC 4051d 18h /mod_sim_exp/trunk/
76 testbench update JonasDC 4054d 05h /mod_sim_exp/trunk/
75 made rw_address a vector of a fixed width JonasDC 4054d 05h /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 4057d 02h /mod_sim_exp/trunk/
73 updated plb interface, mem_style and device generics added JonasDC 4058d 01h /mod_sim_exp/trunk/
72 deleted old resources JonasDC 4059d 01h /mod_sim_exp/trunk/
