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. |

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. |

Fixed a problem whereby block RAM would be declared as a bus error on the
stack, even if the data was valid. |

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 ...) |

Mostly cosmetic changes. The Makefile now builds a couple more programs,
the documentation is better, etc. |

Added a SDSPI scope, and defined which of the four scopes it points to.
(It uses the configuration scopes position, if the configuration scope isn't
defined.) |

Fixes the problem whereby the master counters show when the user counters should
be showing and vice versa. Now the master counters show by default, together
with their correct labels. User counters are still available by pressing
'u' in the debugger, and the master counter display may be returned to by
pressing 'm' in the debugger. |

Comments out the line that caused a compiler warning--setting an unused
variable. Code should be better as a result. |

Now tries to avoid reading from the stack if the stack addresses are already
known to be bad. That way, the debugger tries to preserve any bus error address
already on the buserr device. |

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. |

had been written to the RAM earlier. |

This adds to dumpsdram the capability to run over a port, such as with
busmaster_tb. |

Oops -- the audio was wired audio first then the interrupt controller, not
the other way around. This adjusts regdefs to match what's on the chip. |

A bug fix, although one that rearranges the bus. The first four I/O locations
have been adjusted. The new locations are reflected in wishbone.html. In
addition, the PWM and UART devices no longer create bus errors when accessed.
Finally, this version uses a `define XULA25 to determine whether or not to build
for the XuLA2-LX9 or the XuLA2-LX25. If defined, it will build for the
XuLA2-LX25. If not, for the XuLA2-LX9. The ideal location for this define
would be to place it into your Xilinx configuration, should you wish to build
for the LX25. |

This adds a vastly updated and superious ziprun capability to the repository.
ziprun now accepts ELF program files *only*, reads them, and places them onto
the board. This includes the ability, within the ELF file, of specifying
whether or not the data is sent to block ram, SD ram, or Flash, as well as
the ability of specifying the initial address. (Of course, that's a one time
thing--to always have the same initial address, set the address in
rtl/busmaster.v) |

Some basic updates, to include adding in a missing file (zipstate). Most of
these updates include making sure that the XuLA2 device can be accessed via
the USB. (Prior versions accessed the FPGA via serial port or network ...) |
