94 Optimization on the functionality of the mantissa multiplier... the results are much more precise than last revision... jguarin2002 4800d 14h /raytrac/trunk/fpbranch/
93 New Fpbranch Directory Distribution jguarin2002 4801d 00h /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 4803d 11h /raytrac/trunk/fpbranch/

90 Minor corrections to ema2 zero support jguarin2002 4803d 18h /raytrac/trunk/fpbranch/
89 floating point mult ready jguarin2002 4803d 19h /raytrac/trunk/fpbranch/
88 Exponent Managment Addition: supports now Zero jguarin2002 4803d 21h /raytrac/trunk/fpbranch/
87 For the sake of easyness, mmp is called now mul2 jguarin2002 4805d 21h /raytrac/trunk/fpbranch/
86 For the sake of easyness, mmp is called now mul2 jguarin2002 4805d 21h /raytrac/trunk/fpbranch/
85 get doesnt fit anymore... jguarin2002 4806d 12h /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 4806d 12h /raytrac/trunk/fpbranch/
83 Only to have it as an example of what to do to sign a mantissa jguarin2002 4806d 12h /raytrac/trunk/fpbranch/
