changes in makefile, and fifo's are now also in mod_sim_exp library |

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. |

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 |

updated vhdl files so now different clock frequencies are posible for the core and bus interface. |

AXI-Lite interface updated, now tested and verified on Xilinx FPGA
renamed C_DEVICE parameter, because of conflicts with restricted parameter in xilinx XPS |

/mod_sim_exp/trunk/rtl/vhdl/core |

now using values from mod_sim_exp_pkg instead of direct entity |

/mod_sim_exp/trunk/rtl/vhdl/core |
| 81 |
updated files, now using the components of the mod_sim_exp_pkg instead of direct entity declaration |

/mod_sim_exp/trunk/rtl/vhdl/core |
| 75 |
made rw_address a vector of a fixed width |

/mod_sim_exp/trunk/rtl/vhdl/core |
| 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. |

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. |
JonasDC |
4448d 18h |
/mod_sim_exp/trunk/rtl/vhdl/core |
| 67 |
added memory modules for modulus and operands for FPGA's that support asymmetric memory inferring. |

updated plb interface, now modulus is selectable and, fifo depth is adjustable.
updated makefile with new sources and update component in package |

/mod_sim_exp/trunk/rtl/vhdl/core |

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 |

generic version of the fifo, not device specific anymore, uses dpram_generic
updated comments of RAM templates. |
JonasDC |
4459d 11h |
/mod_sim_exp/trunk/rtl/vhdl/core |
| 59 |
added templates that correctly infer RAM, for dual port en true dual port RAM
added general functions file, (used in the two RAM templates) |
