The core_tb testbench finally passes. It probably doesn't synthesize, or even pass other testbenches, but it passes that one damn it. |

fuck it. All sorts of broken, will try to fix it tomorrow |

Added fetch component for fetching from memory to instruction register
Added additional testing for carryover to make sure it's correct |

Renamed incdec to carryover (see design for why).
carryover should be done, though may change the "straight through on disable" behavior to instead leaving it floating depending on how things go later with coding. |

Added README, LICENSE, and the (so far not created) incdec component |

Added ALU with all the operations we'll need. Synthesizes as well trivially |

registerfile has ports for every register now
makefile now uses GHW file format for gtkwave instead of VCD |

Finally, it synthesizes to BRAM.. Possibly need to fix how the DataOut syncs with WriteEnable and Address though if I plan to both read and write on the same clock edge |

Just committing so I can keep this original that passes simulation, but still synthesizes to LUTs |

Trying to add a byte-enable to the RAM. Used Xilinx's template for it, but ghdl won't pass the testbench |

Added blockram for inferring actual block RAM.
Now we need a memory controller, not a crappy memory emulation thing |

Changed memory to fix bound check error
Decreased size of RAM since 4096 bytes of RAM would require an FPGA with more than 32K flip-flops (mine has ~4000) |

Added super rough design document mainly just for brainstorming |
