Abstract
Mechanisms for aligning enhanced precision vectors based on reduced precision data values are provided. At least one data value, having a first precision type, is received for storing in a vector register. The vector register stores data as a vector having a plurality of vector elements. The first precision type is modified to have a second precision type different in precision than the first precision type to thereby generate at least one modified data value. The at least one modified data value is stored in at least one vector element of the plurality of vector elements. An alignment of the at least one modified data value is determined relative to a boundary of a vector element of the vector register. An alignment operation to re-align the at least one modified data value based on the boundary of the vector element of the vector register is performed.
