Title: Microprocessor
Inventor: DEGUCHI MASASHI
IPC: G06F9/22
Filed: 1983-12-19
Abstract: PURPOSE:To make it unnecessary to store a microprogram regarding a pipeline control in a control storage by providing a microinstruction register, a selector for switching an output of a control information memory, and an FF for controlling said selector. CONSTITUTION:A pipeline register 27 designates three stage pipeline registers, namely, three pipeline registers of an instruction register 21, a control storage address register 23 and a microinstruction register 25, as effective. When an FF29 is set, a counter 28 is preset so as to execute an access to a memory device 30, and when the FF29 is reset, a microinstruction required for a delay control of the pipeline is fetched from a memory device 30. As a result, instead of an output of a usual microinstruction register 25, the microinstruction is sent out to a decoder 26 from the memory device 30, and it becomes unnecessary to store a microprogram in a control storage 24.

Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To simplify a control circuit in which a control signal transmitted between a slave machine and a master machine does not interfere with a sound band by means of a base band system and which corresponds to the control signal. SOLUTION: In a monitor operation, a slave machine requires only a photographing operation by a camera circuit 5 without the need of a speech. Since the sound output of a speaker 10 is not required, the powder of a speaker amplifier 9 is turned off, and the control signal is sent as a power off signal from a master machine and as a signal obtained by discontinuing 30-40 kHz by the single frequency of a sound band. It is detected in remote control IC12 through two wire terminals C1 and C2 on a slave machine-side, it operates on a speaker amplifier SW11 as the control signal and turns off the SW. In a speech operation, the master machine sends a power-on signal (non-signal can be sent as the control signal) from the master machine and the speaker amplifier SW1 is turned on.
