118 fp beta version reached a 17,5% logic cell starting at 450 LEs and finishing in 371 LEs for fadd32 jguarin2002 4758d 20h /raytrac/trunk/fpbranch
117 Official reduction achieved 12% jguarin2002 4759d 02h /raytrac/trunk/fpbranch
116 Official Reduction is 7%: Adder 420 logic cells, trying to reach out at least 20 less cells jguarin2002 4759d 03h /raytrac/trunk/fpbranch
115 Official Reduction is about 7% jguarin2002 4759d 03h /raytrac/trunk/fpbranch
114 lost of time.. jguarin2002 4760d 02h /raytrac/trunk/fpbranch
113 Will end this tomorrow for sure.... anyway i dont think i will got something below 400... jguarin2002 4765d 16h /raytrac/trunk/fpbranch
112 99.7%... almost there jguarin2002 4765d 18h /raytrac/trunk/fpbranch
111 99% of work done jguarin2002 4766d 03h /raytrac/trunk/fpbranch
110 Chopchop 99% jguarin2002 4766d 21h /raytrac/trunk/fpbranch
109 Still working on adder, almost there..... jguarin2002 4767d 15h /raytrac/trunk/fpbranch
108 Ongoing work... 75% jguarin2002 4768d 09h /raytrac/trunk/fpbranch
107 working working and working... jguarin2002 4769d 00h /raytrac/trunk/fpbranch
106 Optimizing Adder.... at a very slow pace... Got to rush jguarin2002 4773d 09h /raytrac/trunk/fpbranch
105 Control... jguarin2002 4784d 08h /raytrac/trunk/fpbranch
104 Square Root and inversion support jguarin2002 4789d 17h /raytrac/trunk/fpbranch
103 Square Root Ok jguarin2002 4790d 00h /raytrac/trunk/fpbranch
102 FP additions done jguarin2002 4790d 00h /raytrac/trunk/fpbranch
100 Additions Ended jguarin2002 4791d 15h /raytrac/trunk/fpbranch
99 Square Root... comin sun.... jguarin2002 4791d 15h /raytrac/trunk/fpbranch
98 Addition Mistery.. Solved jguarin2002 4793d 07h /raytrac/trunk/fpbranch
97 2 floating points operands multiplication done and optimized, correction make on result sign when substracting jguarin2002 4795d 09h /raytrac/trunk/fpbranch
96 2 floating points operands multiplication done and optimized jguarin2002 4796d 18h /raytrac/trunk/fpbranch
95 2 floating points operands addition done and optimized jguarin2002 4796d 18h /raytrac/trunk/fpbranch
94 Optimization on the functionality of the mantissa multiplier... the results are much more precise than last revision... jguarin2002 4798d 15h /raytrac/trunk/fpbranch
93 New Fpbranch Directory Distribution jguarin2002 4799d 01h /raytrac/trunk/fpbranch
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 4801d 12h /raytrac/trunk/fpbranch

90 Minor corrections to ema2 zero support jguarin2002 4801d 19h /raytrac/trunk/fpbranch
89 floating point mult ready jguarin2002 4801d 20h /raytrac/trunk/fpbranch
88 Exponent Managment Addition: supports now Zero jguarin2002 4801d 22h /raytrac/trunk/fpbranch
