114 lost of time.. jguarin2002 4760d 07h /raytrac/trunk/fpbranch
113 Will end this tomorrow for sure.... anyway i dont think i will got something below 400... jguarin2002 4765d 20h /raytrac/trunk/fpbranch
112 99.7%... almost there jguarin2002 4765d 23h /raytrac/trunk/fpbranch
111 99% of work done jguarin2002 4766d 08h /raytrac/trunk/fpbranch
110 Chopchop 99% jguarin2002 4767d 02h /raytrac/trunk/fpbranch
109 Still working on adder, almost there..... jguarin2002 4767d 20h /raytrac/trunk/fpbranch
108 Ongoing work... 75% jguarin2002 4768d 14h /raytrac/trunk/fpbranch
107 working working and working... jguarin2002 4769d 05h /raytrac/trunk/fpbranch
106 Optimizing Adder.... at a very slow pace... Got to rush jguarin2002 4773d 14h /raytrac/trunk/fpbranch
105 Control... jguarin2002 4784d 13h /raytrac/trunk/fpbranch
104 Square Root and inversion support jguarin2002 4789d 22h /raytrac/trunk/fpbranch
103 Square Root Ok jguarin2002 4790d 05h /raytrac/trunk/fpbranch
102 FP additions done jguarin2002 4790d 05h /raytrac/trunk/fpbranch
100 Additions Ended jguarin2002 4791d 20h /raytrac/trunk/fpbranch
99 Square Root... comin sun.... jguarin2002 4791d 20h /raytrac/trunk/fpbranch
98 Addition Mistery.. Solved jguarin2002 4793d 12h /raytrac/trunk/fpbranch
97 2 floating points operands multiplication done and optimized, correction make on result sign when substracting jguarin2002 4795d 13h /raytrac/trunk/fpbranch
96 2 floating points operands multiplication done and optimized jguarin2002 4796d 23h /raytrac/trunk/fpbranch
95 2 floating points operands addition done and optimized jguarin2002 4796d 23h /raytrac/trunk/fpbranch
94 Optimization on the functionality of the mantissa multiplier... the results are much more precise than last revision... jguarin2002 4798d 20h /raytrac/trunk/fpbranch
93 New Fpbranch Directory Distribution jguarin2002 4799d 06h /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 17h /raytrac/trunk/fpbranch

90 Minor corrections to ema2 zero support jguarin2002 4802d 00h /raytrac/trunk/fpbranch
89 floating point mult ready jguarin2002 4802d 01h /raytrac/trunk/fpbranch
88 Exponent Managment Addition: supports now Zero jguarin2002 4802d 03h /raytrac/trunk/fpbranch
87 For the sake of easyness, mmp is called now mul2 jguarin2002 4804d 03h /raytrac/trunk/fpbranch
86 For the sake of easyness, mmp is called now mul2 jguarin2002 4804d 03h /raytrac/trunk/fpbranch
85 get doesnt fit anymore... jguarin2002 4804d 18h /raytrac/trunk/fpbranch
84 Floating Point Adders: (ema3,add3) is an a+b+c adder and (ema2,add2) is an a+b adder. Ema's are blocks to normalize the exponents and shift the mantissas as required, add's are blocks that make the mantissa addition and normalize the result again into a 32 bit IEEE float format jguarin2002 4804d 18h /raytrac/trunk/fpbranch
