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 |

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. |

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. |

big update, the mod_sim_exp core now has a selectable ram structure. a generic ram that should be usable in any fpga, a asymmetric ram that is usable for some devices of altera or xilinx and uses less resources. |

now using a generic description of the ram for the memory. the core now should synthesize for al fpga's, no device specific code anymore. tested and synthesizes for altera and xilinx |
