Decoding predicated-loop instruction and suppressing processing in one or more vector processing lanes

摘要

A data processing system supports a predicated-loop instruction that controls vectorised execution of a program loop body in respect of a plurality of vector elements. When the number of elements to be processed is not a whole number multiple of the number of lanes of processing supported for that element size, then the predicated-loop instruction controls suppression of processing in one or more lanes not required.
