1. A method, comprising: matching a virtual address simultaneously in parallel against a set of a plurality of predetermined rules in identifying one or more storing description parameters for converting the virtual address to a lookup address, with each of the plurality of predetermined rules including a range of one or more virtual addresses stored in a binary or ternary content-addressable memory entries, with said matching operation including performing a single hardware-based content-addressable memory lookup operation simultaneously and in parallel on each of said content-addressable memory entries resulting in a single matching rule, and retrieving said storing description parameters from a location in a storing description parameter storage corresponding to the single matching rule; converting the virtual address to the lookup address based on said identified storing description parameters; and performing one or more data access operations in one or more particular memory units based on the lookup address said converted from the virtual address.
