Abstract
A processing system supports memory access based on distinct memory space access instructions as well as universal access instructions that are independent of memory space partitions. Conventional memory-space dependent instructions, such as MOV, MOVX, and MOVC, provide an optimized addressing scheme, and an extended memory-space independent instruction EMOV provides an optimized code efficiency, processing speed, and ease of code generation. A mapping between the discrete memory space partitions and a “universal” memory space allocation is provided. The processing hardware interprets the universal address to determine the corresponding memory space, and provides the access to an address within that memory space.
