Abstract
A memory management unit (MMU) of a digital processing system operating in a virtual address domain and a physical address domain comprises a memory programmable to store translation mappings between virtual addresses and physical addresses of the processing system. The memory is also programmable to store control codes representative of EDAC protection corresponding to the translation mappings. A method of operating the memory management unit (MMU) comprises the steps of: programming a memory of the MMU with virtual to physical address translation mappings; and programming the memory of the MMU with control codes representative of EDAC protection corresponding to the translation mappings.
Claims16
A memory management unit (MMU) of a digital processing system operating in a virtual address domain and a physical address domain, said MMU including:
- a memory programmable to store translation mappings between virtual addresses and physical addresses of said processing system;
- said memory also programmable to store control codes representative of EDAC protection corresponding to said translation mappings.
A method of operating a memory management unit (MMU) of a digital processing system operable in both virtual and physical address domains, said method comprising the steps of:
- programming a memory of the MMU with virtual to physical address translation mappings;
- and
- programming the memory of the MMU with control codes representative of EDAC protection corresponding to said translation mappings.
