Abstract
A method for managing an external memory of a microprocessor so that the external memory only contains one copy of a common area. By providing an address translator, mapping the page and the address of the common area of the page pointed by a microprocessor to the physical address of the common area of the external memory, using the address translator to translate a page and an address pointed by a microprocessor to a physical address of the external memory, and using the microprocessor to access data stored at the physical address of the external memory; the memory can be more efficiently used.
Claims8
A method for managing an external memory of a microprocessor to achieve more available capacity, the method comprising:
- (a) providing an address translator;
- (b) using the address translator to translate a page of the external memory and an address within the page pointed by the microprocessor to a physical address of the external memory, each common area pointed by the microprocessor being mapped to a section of the external memory;
- and
- (c) using the microprocessor to access data stored at the physical address of the external memory.
