摘要: A division method and circuit performs a division for signed data by adding or subtracting a divisor to or from the dividend or the partial remainder from the division, according to the sign of the divisor or the dividend and the partial remainder to acquire a new partial remainder. The division is repeated a predetermined number of times in which a quotient bit is acquired according to the sign of the acquired partial remainder or the divisor. The dividend is corrected by subtracting 1, which is the significance of an LSB of the corresponding dividend, from the dividend when the sign of the dividend is negative, and the corrected dividend is used for the division processing.

摘要: A multiplication, division and square root extraction apparatus which calculates the solutions to addition, division and square root extraction functions by approximation using iteration has a multiplier, an adder-subtracter and a shifter of prescribed bit width connected to a bus. Iteration is conducted by inputting the output of the multiplier to the adder-subtracter or the shifter and returning the result to the input of the multiplier via the bus. A shifter and an arithmetic and logic unit connected to a second bus connected to the aforesaid bus via a switch have a greater bit width than the prescribed bit width and are used for large scale calculations, thus preventing a reduction in processing speed.

摘要: A microcomputer that is easy to use and connected direct to such memories as dynamic and static RAM's and to other peripheral circuits. The microcomputer has strobe signal output terminals CASH*, CASL* and RAS* for direct connection to a dynamic RAM, and chip select signal output terminals CS0* through CS6* for outputting a chip select signal in parallel with the output from the strobe signal output terminals. The microcomputer further includes address output terminals for outputting a non-multiplexed or multiplexed address signal as needed, and data I/O terminals for selectively outputting the address signal to comply with a multiple-bus interface scheme.

摘要: Even in such an arrangement in which the throttle valve is operated independently of the engine control system, abnormal engine behavior is ensured to be detected such that a necessary fail-safe operation should be taken. The arrangement of the invention is comprised of the electronically controlled throttle system, engine control system and engine speed monitoring unit, wherein the electronically controlled throttle system is allowed to monitor engine behaviors. Thereby, in the case when the throttle valve is operated independently of the engine control system, if its engine behavior becomes abnormal relative to its drive contents, the engine system senses the abnormality, and takes a fail-safe operation such as to stop operation of the throttle valve and the like.
