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 |

DPC changes\n\n\t+ established the DCS system rather than the UCA definitively\n\t+ Rather than usign 4 result queues now theres just a single one, of course 4 times wider, this was made to gain simplicity when writing and reading the RTL description that adapts this 4/3/1 word wide result buffer output into a 1 word wide result buffer input\n\t+ Added the Q1 queue to syncrhonize magnitude and normalization ops, managing them to enter at the sime tame rather than different times, formerly it was implemented by setting the normalization and magnitude results into the results buffers at 25th beat and 20th beat respectively, now both results enter into THE SINGLE RESULT QUEUE at 25th beat. This change also forces that Dot product operation to use the Q1 hardware and entering also at beath 25th into the result queue, it could be done in an earlier beatt (in fact in the 19th) but multiplexation logic would have to be added. |

Check out in the design document for changes made on Load logic, a load chain has been added to Memblock I/O and several memory blocks were removed, under construction, this version WONT in any means work |

raytrac+sg_dma+raytrac. Step One, the DPC is transformed. Now there are five instructions (check the design document), theres no full queue sync event, there are only four result queues and only 3 add fp 32 b adders rather than 4. Even it seems like a reduction has taken place, decodification efforts take place when decoding multiplexation from arithmetic blocks towards the resulting queues |
