ABSTRACT:
An instruction fetcher reads out instructions and data from a memory. The instructions and data are decoded by an instruction decoder. When a data transfer instruction is fed to an input register in a register section, a second execution unit starts an execution, the execution result being then stored in an output register. If any unprocessed data remains in the input or output register, the subsequent data processing is suspended. Input and output register sets and execution sub-units may be provided such that any of these components can be selected depending on the necessary process. Since a given execution is executed by the data transfer instruction, the data can be processed at high speed through a simplified program. Since no specific and additional computation instruction is required, the expandability can be improved.
