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. |
