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. |

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 |

Little changes on full result queue signals codification in order to fix a potential bug that havent beed detected at the time of the change in the code |

Fixed a problem on the writing signal of results queue 5,6 and 7. The error was detected just right when a calculated normalized vector was about to be written in the results queues 5 6 and 7 and the write signals of those were not activated (it would remain in 0), after checking what was the problem, a codification bug was spotted. |

After some raytrac simulation result analysis, some bugs were detected on the decodification of several datapaths. Corrections were done and tested |

Corrections on the moment the dot product and normalization queues are "rd_ack\'ed", they were a cycle earlier than they should causing pipeline desync |

dpc: Signals to eval in functional simulatio. Fix on the codification of the sign applied into the arithmetic block depending on the UCA code of the instruction being excuted. Also a correction was done on the decodification of the result queues write signals. A correction applied on the decodification of the interruptions generated due to full queues. RayTrac: A signal to decode the sign that goes into the addition operations was made as long with its combinatorial operation to calculate it. Fadd32: Signals to eval in functional simulation. An important bug was fixed when decoding the shift to normalize the mantissa of the float number with the minor exponent, that was causing a misscalculation of the normalized mantissa. Arithpack: Formatting of the instruction at function ap_format_instruction fixed due to a change in the opcodes of the unary instructions. |
