摘要： A microcomputer MCU adopting the general purpose register method is enabled to have a small program capacity or a high program memory using efficiency and low system cost, while enjoying the advantage of simplification of the instruction decoding as in the RISC machine having a fixed length instruction format of the prior art, by adopting an instruction format of a fixed length of 2 n bits which is smaller than the length of the maximum data word fed to instruction execution means. The control of the coded division is executed by noting the code bits.

摘要： A circuit and method for performing signed integer division by repeated division processing, in which a new partial remainder is formed by subtracting (or adding) a divisor from (to) a dividend or a partial remainder in accordance with the sign of the dividend or the partial remainder and the sign of the divisor, and a quotient bit is formed on the basis of the sign of the partial remainder and the sign of the divisor, wherein a pre-processing step corrects the dividend by subtracting 1 from the dividend if it is negative, and a post-processing step corrects the quotient formed by the repeated division processing on the basis of its sign.

摘要： Disclosed is a method of controlling the supply of a clock signal to a logic circuit, especially, a logic circuit composed of C-MOS gates for further reducing the power consumption. According to the control method, a clock signal supply inhibit instruction is stored, so that, when this instruction is read out, the supply of the clock signal to the logic circuit is inhibited, or its level is fixed at a specific signal level. In response to the application of an interrupt signal, the clock signal having been inhibited to be supplied to the logic circuit starts to be supplied to the logic circuit again. The circuit region or regions for which the supply of the clock signal is to be inhibited can be freely selected for the purpose of control. Thus, the method is especially effective when it is desired to closely control the saving of power consumed by the logic circuit.

摘要： Disclosed is a method of controlling the supply of a clock signal (90x, 91x, 92x) to a logic circuit, especially, a logic circuit composed of C-MOS gates for further reducing the power consumption. According to the control method, a clock signal supply inhibit instruction is stored, so that, when this instruction is read out, the supply of the clock signal to the logic circuit is inhibited, or its level is fixed at a specific signal level. In response to the application of an interrupt signal, the clock signal having been inhibited to be supplied to the logic circuit starts to be supplied to the logic circuit again. The circuit region or regions (22, 90, 91) for which the supply of the clock signal is to be inhibited can be freely selected for the purpose of control. Thus, the method is especially effective when it is desired to closely control the saving of power consumed by the logic circuit.
