Apparatus and method for processing input operand values

A method of processing an input operand value having a plurality of portions, comprising:

• providing a set of vector data storage elements, each vector data storage element providing a plurality of sections for storing data values, a plurality of lanes being provided within the set where each lane comprises a corresponding section from each vector data storage element;
• performing an arithmetic operation on the input operand value by performing an independent arithmetic operation on each of the plurality of portions, in order to produce a result value comprising a plurality of result portions;
• and
• storing the result value within a selected lane of said plurality of lanes, such that each result portion is stored in a different vector data storage element within the corresponding section for the selected lane.

A non-transitory, computer-readable storage medium storing a computer program for controlling a host data processing apparatus to provide an instruction execution environment comprising:

• a set of vector data structures, each vector data structure providing a plurality of sections for storing data values, a plurality of lanes being provided within the set where each lane comprises a corresponding section from each vector data structure;
• processing program logic to perform an arithmetic operation on an input operand value comprising a plurality of portions, by performing an independent arithmetic operation on each of the plurality of portions, in order to produce a result value comprising a plurality of result portions;
• and
• storage program logic to store the result value within a selected lane of said plurality of lanes, such that each result portion is stored in a different vector data structure within the corresponding section for the selected lane.
