Structure for cache function overloading

Abstract

A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design is provided. The design structure generally includes a system that includes a cache that stores information in a cache line for processing, wherein the cache line includes at least a first field configured to store an instruction or data and at least a second field configured to store parity information, a parity register that include a parameter indicative a whether parity generation and checking is disabled for the information in the cache line, and a processor that sets the second field in the cache line to include a value, which indicates a corresponding action to be performed, when the parameter in the parity register indicates that parity generation and checking is disabled for the cache line.

Dependencies are inferred from the claim text.
