107 working working and working... jguarin2002 4855d 11h /raytrac/trunk/fpbranch/add/ema32x2.vhd
106 Optimizing Adder.... at a very slow pace... Got to rush jguarin2002 4859d 19h /raytrac/trunk/fpbranch/add/ema32x2.vhd
102 FP additions done jguarin2002 4876d 11h /raytrac/trunk/fpbranch/add/ema32x2.vhd
100 Additions Ended jguarin2002 4878d 01h /raytrac/trunk/fpbranch/add/ema2.vhd
98 Addition Mistery.. Solved jguarin2002 4879d 17h /raytrac/trunk/fpbranch/add/ema2.vhd
97 2 floating points operands multiplication done and optimized, correction make on result sign when substracting jguarin2002 4881d 19h /raytrac/trunk/fpbranch/add/ema2.vhd
95 2 floating points operands addition done and optimized jguarin2002 4883d 05h /raytrac/trunk/fpbranch/add/ema2.vhd
93 New Fpbranch Directory Distribution jguarin2002 4885d 12h /raytrac/trunk/fpbranch/add/ema2.vhd
91 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 4887d 23h /ema2.vhd
90 Minor corrections to ema2 zero support jguarin2002 4888d 06h /ema2.vhd
88 Exponent Managment Addition: supports now Zero jguarin2002 4888d 09h /ema2.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 4891d 00h /ema2.vhd
