PROCESSOR FOR PROCESSING DATA ACCORDING TO DIFFERENT MODES, AND SUITABLE MULTIPLYING DEVICE FOR SUCH A PROCESSOR

摘要

A processor for carrying out a calculation mode from a selected plurality of different modes. The processor includes a clock pulse generator which generates clock pulses in an order for processing subsequent data. A mode circuit is included for detecting a mode declaration instruction. The mode declaration instruction is decoded to select a different clock pulse cycle for each different mode selected. Mode control signals and the selected clock pulse cycle are applied to a control code and borrow management circuit to enable the arithmetic and logic unit to carry out one or more operations of the mode control signals.
