Method and apparatus for RAM emulation using a processor register set

摘要

An apparatus and method for accessing a writeable storage in a processor-based system. The apparatus comprises at least one writeable storage element and memory for storing instruction sequences by which the processor-based system is processed, that has a writeable storage location. A processor is coupled to the writeable storage element and executes the stored instruction sequences. The stored instruction sequences include process steps to cause the processor to: (a) detect an access to the writeable storage location; (b) transfer the access to the writeable storage location to an access to the writeable storage element; (c) process an instruction sequence corresponding to the access to the writeable storage element.
