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

90 reverted changes from previous revision, updated AXI version with testbench JonasDC 4177d 14h /mod_sim_exp/trunk/rtl/vhdl/core/operand_ram.vhd
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 4241d 12h /mod_sim_exp/trunk/rtl/vhdl/core/operand_ram.vhd
39 changed files to remove warnings from synthesis
last cell logic is simplified because of redundant logic
JonasDC 4404d 11h /mod_sim_exp/trunk/rtl/vhdl/core/operand_ram.vhd
3 updated vhdl sources with new header according to OC design rules and formated code
added makefile and simulation input file for testbench simulation

2 First version of VHDL source(working), still contains xilinx primitives and needs to be updated to the OpenCores design rules.. JonasDC 4429d 19h /mod_sim_exp/trunk/rtl/vhdl/core/operand_ram.vhd
