Abstract

PURPOSE:To process a polynomial without generating an idle time in the memory access, by providing additionally an extended data register where the output result of an operator is stored and an extended arithmetic unit which executes the operation processing for data of this register. CONSTITUTION:Data can be transferred mutually between the second data register 5 and the second arithmetic unit 6, and data stored in the register 5 is certainly processed by said unit 6. Data processed by the first arithmetic unit 3 is one-way and is stored in the register 5 to reduce the quantity of hardware. Data processed by said unit 6 is one-way and is stored in the first data register 2 and connot be transferred in the reverse direction. The register 5 cannot transmit and receive data to and from a main storage device 1. The operation for a polynomial is executed efficiently by these additionally provided register 5 and said unit 6.
