Abstract
A digital processing system includes an external memory for the storage of program instructions for use with a separate processor that internally contains a memory for temporary storage, an arithmetic and logic means, a register set, control and timing circuitry, and two sets of data paths. The first set of data paths provide access to the external memory for transfer of instructions from the external memory to the processing unit. The second set of data paths provide for the internal routing of instructions data and addresses within the processor unit itself. The data structure for the first set of data paths is different than that for the second set of data paths, providing for an external data structure that is different than the internal data structure of the processor.
