Manipulation of data

摘要

A computer and a method of operating a computer is disclosed which allow manipulation of data values in the context of the execution of so-called "packed instructions". Packed instructions are carried out on packed operands. A packed operand comprises a data string consisting of a plurality of sub-strings, each defining a particular data value or object. The invention relates to a restructuring instruction which allows objects to be reorganised within a data string thereby minimising loading and storing operations to memory.
