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. |

/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 |

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 |
4088d 01h |
/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) |

/mod_sim_exp/trunk/rtl/vhdl/core/ |
| 39 |
changed files to remove warnings from synthesis
last cell logic is simplified because of redundant logic |

deprecated design files because of new pipeline structure, will be removed shortly |

changed names of some generics of the multiplier.
moved the parameters for the core to the package of the core
testbench now uses this parameters to adapt to different bit widths
and new systolic pipeline now supports split or single pipeline |

/mod_sim_exp/trunk/rtl/vhdl/core/ |
| 36 |
found bug in new pipeline structure, now working properly. (tested in sim)
mod_sim_exp_core uses new flexible pipeline as default. |

operand memory now supports custom operand widths, the internal memory stays the fixed 1536 bit, but the bus width is now adjustable to any size below. |

default pipeline changed to old version, there seems to be an occasional error with new version. |

new systolic pipeline structure now has split pipeline support, tested and verified in simulation. the core now uses this pipeline by default. |
JonasDC |

first version of new pipeline design. allows for more flexibility in nr of stages.
does not support split pipeline support yet. currently only works for single pipeline |
