Abstract
A system and method of accessing a memory location within a system having a processor and a plurality of memory locations separate from the processor. The system includes a plurality of external registers which are connected to the processor over a data bus, address translation means, connected to the processor over the data bus and an address bus, for calculating, based on an index written to the data bus, an address associated with one of the memory locations, and transfer means, connected to the plurality of external registers, for transferring data between the addressed memory location and one of the external registers.
