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 3926d 18h /mod_sim_exp/trunk/rtl/vhdl/ram/dpramblock_asym.vhd
89 updated vhdl files so now different clock frequencies are posible for the core and bus interface. JonasDC 3990d 16h /mod_sim_exp/trunk/rtl/vhdl/ram/dpramblock_asym.vhd
83 now using values from mod_sim_exp_pkg instead of direct entity JonasDC 4000d 03h /mod_sim_exp/trunk/rtl/vhdl/ram/dpramblock_asym.vhd
66 added asymmetric ram structures to support a more performant ramstyle.
defined for xilinx and altera, not tested with other tools.
