Abstract
Virtual memory pre-fetch requests are generated for a virtual memory and a multiple port memory management unit (MMU) circuit. Virtual memory access requests sent to a particular port of the MMU circuit are monitored. In response to the satisfaction of a trigger condition, virtual memory pre-fetch requests are generated and transmitted to the MMU circuit using the particular port. Physical access requests from the MMU circuit are monitored for physical addresses corresponding to the virtual memory pre-fetch requests. The physical access requests corresponding to the virtual memory pre-fetch requests are filtered.
