vhdl and verilog implementation of floating point adder ieee754

IEEE 754 floating-point standard • Leading “1” bit of significand is implicit • Exponent is “biased” to make sorting easier – all 0s is smallest exponent all 1s is largest – bias of 127 for single precision and 1023 for double precision – summary: (–1)sign × (1+significand)...
