Abstract: A microcomputer includes a CPU, multiple resources, and an output circuit having an address decoder. The CPU outputs an address signal to the address decoder. The address decoder decodes the address signal and the output circuit outputs a select signal to at least one of the resources in accordance with the decoded address signal. Each of the resources is writable by the CPU when receiving the select signal. When the address signal indicates a predetermined address, the output circuit outputs the select signal to at least two of the resources at a time. Thus, data can be written to the multiple resources at a time. Therefore, the CPU can write the data to the multiple resources within a reduced time by using the output circuit.

Abstract: A single-chip microcomputer includes a logic circuit, a CPU and a flip-flop for synchronizing an interrupt-request signal, which is supplied by the logic circuit to the CPU, based on a clock signal. A multi-chip emulation apparatus comprises a peripheral evaluation chip, a CPU evaluation chip and a device, which are used for emulating functions of the logic circuit, the CPU and the flip-flop respectively. When the multi-chip emulation apparatus is used for emulating functions of the single-chip microcomputer in the development, the device for emulating functions of the flip-flop synchronizes the interrupt-request signal to absorb a delay time incurred by the interrupt-request signal due to a physical distance between the peripheral evaluation chip and the CPU evaluation chip so that an interrupt-handling timing in the emulation matches an interrupt-handling timing in the real operation of the single-chip microcomputer.

Abstract: Signal sampling transistors, to which signals to be sampled are coupled under the control of a first gate signal, and which couples these signals to holds circuits according to the first gate signal, are provided. A switching circuit for differentially switching the signal sampling transistors to complementarily turn off one of these transistors is also provided. This switching circuit includes transistors, one of which is turned on while the other is turned off according to a second gate signal. The individual switching circuit transistors are connected to the respective sampling transistors. With this arrangement, of the sampling transistors one to which the "on" state one of the switching circuit transistors is connected is turned off while the other is turned on. Thus, the conduction state of the sampling transistors for coupling the aforementioned signals to be sampled to the hold circuits can be forcibly controlled by the second gate signal irrespective of the first gate signal.

Abstract: An output circuit and a biasing circuit for biasing an oscillation circuit comprise a current mirror circuit. The DC level of the output signal from the oscillation circuit is level shifted by controlling the current of the current mirror circuit comprising the biasing circuit and the output circuit. This control is performed by suitably determining the number of diodes and the resistances of the resistors making up the current mirror circuit. The biasing circuit of the oscillation circuit may thus be utilized as the level shifting circuit, the DC level of the output signal of the oscillation circuit may be set to a predetermined level, and fluctuations in the duty ratio of the oscillation output may be suppressed.

Abstract: Horizontal sync signal is applied as a reference pulse signal to a first input terminal of a phase detector and is also applied as a gating pulse to a gate circuit. Output of a frequency divider which divides the frequency of the output of a VCO is applied as a comparison pulse to a second input terminal of the phase detector. In the phase detector, a phase detection pulse having a pulse width proportional to the phase difference between the reference pulse and the comparison pulse is obtained. This phase detection pulse is applied through a buffer to a gate circuit. In the gate circuit, the current path from the phase detection pulse input terminal to the output terminal is held conductive during the period of the gating pulse, and during this period an output pulse containing as a component thereof the phase detection pulse mentioned above is obtained. This output pulse is smoothed through a filter to be applied as an oscillation frequency control voltage input to the VCO.

Abstract: DC control signals responsive to ACC voltages are applied to a color signal amplifier, to which recording and reproducing color signals are applied, to control the operation of the color signal amplifier to recording or reproducing mode. Such control is attained by using color killer signal responsive to mode changeover and ACC detector signals which serve to assign the color signal amplifier to recording or reproducing mode. Color signals are obtained from the output terminal of the color signal amplifier in both modes. In the case of recording mode, essentially undesirable recording color signals appearing to the output terminal of the color signal amplifier are by-passed by a low-pass filter, and only ACC detector voltages which are used as color killer signals are supplied to a mixer circuit which mixes brightness and color signals to generate composite color signals to be recorded.
