118 fp beta version reached a 17,5% logic cell starting at 450 LEs and finishing in 371 LEs for fadd32 jguarin2002 4725d 16h /raytrac/trunk
117 Official reduction achieved 12% jguarin2002 4725d 23h /raytrac/trunk
116 Official Reduction is 7%: Adder 420 logic cells, trying to reach out at least 20 less cells jguarin2002 4726d 00h /raytrac/trunk
115 Official Reduction is about 7% jguarin2002 4726d 00h /raytrac/trunk
114 lost of time.. jguarin2002 4726d 23h /raytrac/trunk
113 Will end this tomorrow for sure.... anyway i dont think i will got something below 400... jguarin2002 4732d 12h /raytrac/trunk
112 99.7%... almost there jguarin2002 4732d 15h /raytrac/trunk
111 99% of work done jguarin2002 4733d 00h /raytrac/trunk
110 Chopchop 99% jguarin2002 4733d 18h /raytrac/trunk
109 Still working on adder, almost there..... jguarin2002 4734d 11h /raytrac/trunk
108 Ongoing work... 75% jguarin2002 4735d 06h /raytrac/trunk
107 working working and working... jguarin2002 4735d 21h /raytrac/trunk
106 Optimizing Adder.... at a very slow pace... Got to rush jguarin2002 4740d 06h /raytrac/trunk
105 Control... jguarin2002 4751d 04h /raytrac/trunk
104 Square Root and inversion support jguarin2002 4756d 14h /raytrac/trunk
103 Square Root Ok jguarin2002 4756d 21h /raytrac/trunk
102 FP additions done jguarin2002 4756d 21h /raytrac/trunk
101 theres a new command to offset the first address in the file jguarin2002 4758d 11h /raytrac/trunk
100 Additions Ended jguarin2002 4758d 12h /raytrac/trunk
99 Square Root... comin sun.... jguarin2002 4758d 12h /raytrac/trunk
98 Addition Mistery.. Solved jguarin2002 4760d 04h /raytrac/trunk
97 2 floating points operands multiplication done and optimized, correction make on result sign when substracting jguarin2002 4762d 05h /raytrac/trunk
96 2 floating points operands multiplication done and optimized jguarin2002 4763d 15h /raytrac/trunk
95 2 floating points operands addition done and optimized jguarin2002 4763d 15h /raytrac/trunk
94 Optimization on the functionality of the mantissa multiplier... the results are much more precise than last revision... jguarin2002 4765d 12h /raytrac/trunk
93 New Fpbranch Directory Distribution jguarin2002 4765d 22h /raytrac/trunk
92 Optimizations made on ema2 and ema3: First One, ema3 and ema2 both now has a 4 pipeline, this equalization has saved lots of registers. Second One: Shifters to denormalize mantissas before addition are implemented with multipliers and inverting the bits direction in the bit vectors, resulting in a saving of resources of 332->253 LEs in ema2 (23% saving) and 608->408 LEs in ema3svn status (32% saving) jguarin2002 4768d 09h /raytrac/trunk

90 Minor corrections to ema2 zero support jguarin2002 4768d 16h /raytrac/trunk
89 floating point mult ready jguarin2002 4768d 17h /raytrac/trunk
