widenuf

speculable  exu stream  exu block  compute phase   operation   in the unsigned fixed point value domain  

native on: all

Double the scalar width of an unsigned fixed point value.

The reason a special widen for fixed point is needed is because the fixed point is defined relative to the most significant side. Widening increases precision, but doesn't extend the value range.

The natively available byte widths on all Cores are 1, 2, 4, 8, and on the high end also 16.
