speculable exu stream exu block compute phase operation in the unsigned integer value domain
native on: all
Unsigned integer reciprocal dividion. Helper operation for software division implementation.
This operation creates a seed value for Newton-Rapheson, or other, iterative division.
operands: like Identity [xx:x]
