93 New Fpbranch Directory Distribution jguarin2002 4902d 05h /raytrac/trunk/fpbranch/add/ema3.vhd
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 4904d 17h /ema3.vhd

90 Minor corrections to ema2 zero support jguarin2002 4905d 00h /ema3.vhd
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 4907d 18h /ema3.vhd
