Needed to play with subtle timing to get this to build. Expect me to play
with these two clock numbers more. |

Cosmetic (minor) update. |

Massive logic simplification. This is also the first (verified) working
version. |

Fixes the debug ack line, so it no longer acks when there isn't a dbg_stb.
Fixed the multiply option parameter, so it sets a 3-clock multiply properly.
Adjusted the watchdog timer so that it now produces a timer that doesn't
reload--since this is pointless for a watchdog. Finally, connects a reset
line to the DMA, to make certain that resetting the CPU will also reset any
ongoing DMA operation. |

Simplifies logic, and guarantees that the minimum set value will always
produce an int. For example, if the count was X before, setting X-1 wouldn't
produce an interrupt since it had passed. Now it produces an interrupt, and
keeps the next interrupt valid. |

Makes the auto-reload feature a parameterized (generic) feature, so the same
code will work for both auto-reloadable and non-autoreloadable (i.e. watchdog)
timers. |

Removed the pipe logic from the non-pipelined version, and made the NOOP a
specific ALU instruction so that the PC is always properly updated. |

Fixed the timing control wires: busy and valid will never both be true. Busy
will be true (now) until valid is asserted, and busy will never not be
asserted until valid is true. |

LONG_MPY upgrade. This is part of swapping out the LDIHI instruction for a
MPY, and the MPYS and MPYU instructions for MPYSHI and MPYUHI respectively. |

RX. |

Brings code in line with the OpenCores core: parameterizes the reload value,
and the number of bits in the timer. |

This brings the XuLA2-LX25 SoC up to speed with the rest of the ZipCPU, and
prepares it for the 32x32 bit multiply instruction set change. |

Lots of bug fixes. The ugliest were in the prefetch cache, where instructions
from one cache line were being issued as valid in another. Other fixes include
pipeline fixes so that LOD (Rx),Rx; LOD(Rx),Rx works, and more. Finally, the
decode was adjusted so that brev no longer affects the flags. |

Cleaned up the documentation a touch. It no longer reads like the bugs I used
to debug are still being debugged ... |

Fixes the "NAN" clocks/second output, as well as making input timing come closer
to a realistic timing. (I actually don't know what timing the JTAG port is
providing, but ... the new timer is closer.) |

This is a bug fix release--fixing the bug that kept dumpsdram.cpp/wbsdram.v
from working when long pipelined reads were interrupted by the necessity of
a pair of refresh cycles. |
