FpuUnpackerPlugin

class FpuUnpackerPlugin extends FiberPlugin

Recode the floating point number comming from the register file to get rid of subnormal numbers by extending the exponant range instead. Getting ride of subnormal helps various floating point operations, as it ensure that the range of the mantissa stay between [1.0, 2.0[

When a subnormal number come in, the pipeline will be stuck for a few cycles in order to preserve the FMax.
