Lots of changes. The biggest are to the CPU: MPYxHI instructions are now
verified to be working, ILLegal instructions stop at the right location,
the STEP bit no longer self-clears, etc. Other changes cleaned up the
internal documentation and removed parameters that should only have local
scope from the global parameter list. The NEW_INSTRUCTION_SET was also
removed from the CPU, since ... it's been new for too long to really be new
anymore. |

Updates, to include new README and bench/cpp/Makefile that doesnt depend upon
a static VERILATOR_ROOT location. |

Added ZipBones to the list of dependencies, so this will (should) build
properly for the XULA9 as well as the XULA25. |

Lots of updates, mostly focused on getting the XuLA board and CPU able to pass
a comprehensive test suite. At this point, everything passes and logic usage
is down even. Among the few changes includes the "break" bit in the uCC
register, used to indicate a switch to supervisor mode occurred as a result
of a user break, and the ability for the supervisor to clear the instruction
cache. |

This continues the updates to the wishbone-uart conversion. It fixes several
bugs within wbuexec, and pipelines the compression scheme. Further, the
read codeword was adjusted so that a read of 8 can be requested with six-bits,
rather than requiring 12. Likewise, the dependence upon the read of 8 on
incrementing the address pointer has been removed. All told, the design
builds for a 200MHz Artix-7, and it has been tested with the CMod-S6. (Writing
flash seems to be one of the most comprehensive tests ...) |

Updated documentation. The documentation for these now also reflects that
these were drawn from an FPGA Library project, that is shared among many
FPGA builds. |

Fixed the `defines at the top so that this can be built without any CPU.
This was then used to measure the impact of the CPU on the entire build, as
you could now build with no CPU, and then with a CPU to compare. |

Includes updates so this can run at higher clocks speeds within an FPGA. |

Includes high-speed updates. rxuart and txuart will now run at 200MHz on
an Artix-7, so should not impact timing (any more) on the XuLA platform. |

made in 2016. |

Reads and writes to the SD over SPI port now work. The card appears, as of now,
to be fully functional. |

Bug fixes, following the adf_ce logic combining ALU/DIVIDE/FPU pipeline logic
into one register, this fixes that logic so that instructions without their
condition fulfilled are still "executed" and marked as done. |

to use the SPI port. |
