ABSTRACT:
An MMU provides services at a cost more directly proportional to the needs of the system. According to one aspect, the MMU provides both address translation and sophisticated protection capabilities. Translation and protection are desirable when applications running on the processor are not completely debugged or trustable, for example. According to another aspect, a system for configuring the MMU design according to user specifications and system needs is provided. The MMU configurability aspects enable the system designer to configure MMUs having run-time programmability features that span the range from completely static to completely dynamic. In addition, the MMU can be configured to support variable page sizes, multiple protection and sharing rings, demand paging, and hardware TLB refill, for example.
