Accessing value for local variable from function call stack upon offset matching with instruction extracted stack pointer offset or from cache

A method of accessing a memory according to a processor instruction, the method comprising:

• an offset extracting operation in which an offset value is extracted from a stack pointer offset indicating a local variable in the processor instruction;
• and
• a local variable loading operation in which a local variable value is loaded by comparing the extracted offset value with an offset value of each item of a local stack storage, determining whether an item corresponding to the extracted offset value is present in the local stack storage, and allowing a processor to access the local stack storage or a cache memory according to a determining result.
