ABSTRACT:
A method and system for virtual memory translation of data represented in a multidimensional coordinate system when the physical memory may be located in more than one physical memory location. The translation of one or more virtual addresses into one or more accesses to one or more physical memories is achieved by representing each address of each element of a memory of the one or more physical memories as a point in a Cartesian coordinate system wherein consecutive points in the Cartesian coordinate system represent virtual memory addresses corresponding to elements from different physical memories of the one or more physical memories. Points in the Cartesian coordinate system are translated into one or more corresponding physical memory addresses, and read or write operations may be performed relative to these physical memory addresses. Multiple read or write operations may be performed during a single clock cycle through the use of parallel accesses of the one or more physical memories. Alternatively, multiple read or write operations may be performed in a pipelined architecture.
