Changed the directory structure a little bit, there is now wide arith (which encapsulates in a single RTL 3 adders or 3 adders |

AS1 produced an unnoticed delay, the compiler geenerated an extra stage..... so a delay constant was added to sync this extra stage with the operation via ssync_chain |

RC 1.0 Previous rev(228), is functional and even more than this one, but is bigger and is for debugging |

Total RtEngine Hardware, BUT, problems with interconnection... perhaps theres a problem with long path on ssumando5 |

Fixed a BUG where big differences betweeen exponents difference suffered from miss-signedness because of the width of the result was 1 bit narrower, and still its highest significant bit was taken as the sign, in result big differences in where taken as negative results... leading to situations like A+0=0 cause the exponent chosen as the big one was the zero's (-127) leading to an unexpected 0 in the result. The bug was fixed by correcting the signedness of the operation and making the result less narrower in one bit. |

The change in sqrt and inv is about the path of the files with the data memory. dpc has been changed by ap_n_dpc and there was an error on RayTrac related to the load sync chain: the loading of Dot product Operation was being carried out as if it was an unary operation rather than a two operands operation |

At the moment memblock.vhd described 3 things: an input params queue (discarded, input control is made with master_readdatavalid signal and load_sync_chain) a load sync_chain(implemented in raytrac.vhd) and 4 result queues, which were implemented as a single result queue in raytrac.vhd).\n\n\ncustom_counter and Raytrac_control, are no longer needed |
