selective bypassing of a multi-port register file

摘要

A multi-port register file may be selectively bypassed such that any element in a result vector is bypassed to the same index of an input vector of a succeeding operation when the element is requested in the succeeding operation in the same index as it was generated. Alternatively, the results to be placed in a register file may be bypassed to a succeeding operation when the N elements that dynamically compose a vector are requested as inputs to the next operation exactly in the same order as they were generated. That is, for the purposes of bypassing, the N vector elements are treated as a single entity. Similar rules apply for the write-through path.
