Electronic multiple function watch

Abstract

Abstract PURPOSE:To simplify the constitution of an electronic multiple function watch by providing an information processing control high speed timing pulse generator for processing information at high speed to thereby process the information in series. CONSTITUTION:A high frequency oscillator 15 for generating higher frequency control pulse than that from a standard time pulse generator 1 is started through a starting circuit 3 by the signal corresponding to a key operation for outputting from a key input circuit 2 connected to the generator 1 upon operation of a key, and program is read from a ROM5 responsive to the key operation through a program counter 4. Information is shortly processed via a RAM6, an arithmetic circuit 7, and discriminator 8 or the like by the high speed pluse from the oscilllator 15 with the result that the time is displayed on a display unit 13. This high speed short time processor can serially process the information with one arithmetic circuit and memory commonly used to thus simplify the multiple functions imparted with stop watch, alarm functions.
