94 Optimization on the functionality of the mantissa multiplier... the results are much more precise than last revision... jguarin2002 4752d 11h /
93 New Fpbranch Directory Distribution jguarin2002 4752d 21h /
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 4755d 08h /

90 Minor corrections to ema2 zero support jguarin2002 4755d 15h /
89 floating point mult ready jguarin2002 4755d 16h /
88 Exponent Managment Addition: supports now Zero jguarin2002 4755d 18h /
87 For the sake of easyness, mmp is called now mul2 jguarin2002 4757d 18h /
86 For the sake of easyness, mmp is called now mul2 jguarin2002 4757d 18h /
85 get doesnt fit anymore... jguarin2002 4758d 09h /
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 4758d 09h /
83 Only to have it as an example of what to do to sign a mantissa jguarin2002 4758d 09h /
82 FPBRANCH releaseeeesvn add fpbranch/get.vhd fpbranch/sm.vhd fpbranch/slr.vhd fpbranch/mmp.vhd svn add fpbranch/get.vhd fpbranch/sm.vhd fpbranch/slr.vhd fpbranch/mmp.vhd svn add fpbranch/get.vhd fpbranch/sm.vhd fpbranch/slr.vhd fpbranch/mmp.vhd jguarin2002 4761d 04h /
81 Almost There jguarin2002 4765d 02h /
80 not a revision jguarin2002 4765d 18h /
79 I can't use a 20 bits mantissa.... eliminating optimization jguarin2002 4769d 13h /
78 Metamorphosis jguarin2002 4777d 02h /
77 Now support for addition and substraction of A(7,10) component vectors jguarin2002 4777d 15h /
76 Upgrade para obtener una mantissa de 20 bits jguarin2002 4779d 13h /
75 Optimization done on matissa lenght for x**-1 and x**0.5, getting a longer mantissa of 20 bits instead one of 18 bits jguarin2002 4781d 08h /
