  • Method and apparatus for disabling and diagnosing cache memory storage locations
    Patent number: 4357656
    Abstract: In a data processing system having a main memory containing addressable main memory storage locations, and also having a processor with a cache memory containing addressable cache memory storage locations, signals representative of predetermined addressable cache memory storage locations desired to be intentionally disabled by an operator of the data processing system are compared with signals representative of an addressable main memory storage location being addressed by the processor during the execution of a program instruction. The data processing system is then caused to access the addressable main memory storage location when the signals representative of the predetermined addressable cache memory storage locations are in a predetermined fixed relationship with the signals representative of the addressable main memory storage location being addressed by the processor during the execution of the program instruction.
