Added a new multiply testbench. Other changes were necessary to follow. |

187 |
Updated to match changed register definitions within the core. |

Now allows profile dumping for ELF executables. |

Now includes the proper flags for building with ELF executable file support. |

Now supports building a simulator that can load ELF files, such as GCC and/or
binutils will produce. |

Improved debug trace quality, for finding bugs after the fact. |

/zipcpu/trunk/bench/cpp |
154 |
Added timing checks on the busy and valid signals: either one of the two is
valid, or the whole is idle. |

Updated the Makefile documentation and the all target. |

Minor changes to get LONG_MPY working, and adjust the documentation. |

Cleans up div_tb a bit, causing it to write SUCCESS out if successful and
abort if not. |

Minor changes, but fixes build of zippy_tb.cpp. |

Working updates, to keep this up to date with the RTL code. |

Fixed some nasty early branching bugs. Adjusted the Makefile to declare that
cpudefs.h was automatically generated from cpudefs.v, and made sure that
zipbones included the cpudefs.v so it could get the DEBUG_SCOPE define.
In addition, the test.S was updated to test long jumps, the early branching
bug we found, and all three early branching instructions: ADD #x,PC, LOC(PC),PC,
and LDI #x,PC. |

Adjusted the operator input line to reflect actual logic inputs, rather
than the registered inputs which may have been out of date. (Indeed, they
were out of date for the bug I was chasing and fixed ...) |

First check-in: the test bench for the divide instruction. |

The biggest change here was to zippy_tb, to make it more similar to the debugger
and to make it work with VLIW-type instructions. |
dgisselq |
3212d 14h |
/zipcpu/trunk/bench/cpp |
75 |
Modified for VLIW instructions. |

This implements the "new Instruction Set" architecture for the Zip CPU. It's
a massive change set, that touches just about everything but probably not
enough of everything. Please see the spec.pdf for a description of this
new architecture. |

Added a rudimentary profiling support to the simulator. |

Some bug fixes to the dhrystone benchmark, and some compile time defines for
the test bench processor. Of the most important note is the fix to detect
lockups on the debug/wishbone bus--that has been a real help in getting the
ZipCPU installed and the debugger working on the various boards I'm working
with. (i.e., it's helped me find and figure out why/when things haven't worked)
Of other note is the new 'G' key in the testbench code, to cause the test
bench to run without user interaction until the next keystroke. This is
very valuable in long programs, as it makes getting to/from breakpoints
easier (i.e. you don't have to wait as long, hit 'G', breathe, hit 'space'
and you're there). |
