Abstract
A method of translating a virtual address into a physical memory address in an ARM System Memory Management Unit version 3 (SMMUv3) system includes searching a Configuration Cache memory for a matching tag that matches an associated tag upon receiving the virtual address and the associated tag, and extracting, in a single memory lookup cycle, a matching data field associated with the matching tag when the matching tag is found in the Configuration Cache memory. A matching data field of the Configuration Cache memory includes a matching Stream Table Entry (STE) and a matching Context Descriptor (CD), both associated with the matching tag. The Configuration Cache memory may be configured as a content-addressable memory. The method further includes storing entries associated with a multiple memory lookup cycle virtual address-to-physical address translation into the Configuration Cache memory, each of the entries including a tag, an associated STE and an associated CD.
