Abstract
PURPOSE:To enable the signal processing of double speed recording, double speed reproducing, simultaneous monitoring and simultaneous recording/reproducing through one LSI system by sharing memory and digital signal processor with operation and reproducing operations and operating a digital signal processor with time-division and double speed by the program corresponding to an action mode. CONSTITUTION:The memory and the digital signal processor are jointly shared by the recording operation and the reproducing operation, and the digital signal processor is operated by the program of recording and the program of reproducing, and the program of recording and the program of reproducing are executed in the time division, the double speed and so on, correspondingly to the operation mode. The memory to store record data or reproduction data is made to have double as large capacity as ordinary one, and in the double speed recording, the double speed reproducing, etc., the processings of the coding and the decoding of an error correction code are superposed with each other, but in this case, a time division-like processing is executed, and the processings of the coding and the decoding are executed without trouble. Thus, the formation of multifunction is possible through the same circuit scale as a current one.
