  • Patent number: 5729764
    Abstract: A bus interface circuit which can suppress generation of noise includes, between an internal data bus and an external data bus, an AND gate and output buffer connected in parallel with an input buffer. A control signal a is supplied to a control terminal of the output buffer and an inverted signal of the control signal a is supplied to a control terminal of the input buffer. A control signal b is supplied to one input terminal of the AND gate. When no access request is made to an external RAM and external ROM, a CPU enables the control signals a and b to be output as a high-level and a low-level signals, respectively. At that time, a respective output buffer enables corresponding data to pass through, but data on the internal data bus is not output to the external data bus when the AND gate is placed in closed state.

  • Patent number: 5726371
    Abstract: In a musical tone waveform generation apparatus for outputting musical tone signals generated by a software program at predetermined time intervals, sound source methods can be selected in units of tone generation channels. In the musical tone waveform generation apparatus, the sound source method or the tone color of a musical tone signal to be output is determined in accordance with performance data (pitch data, touch data, music part data, and the like). A musical tone signal is generated by CPU upon execution of a sound source processing program, associated with a modulation method stored in a memory. The generated musical tone signal is output at predetermined time intervals. As for sound source processing based on the modulation method, at least one operator processing, and algorithm processing for determining an input/output relationship among the operator processing operations are independently executed.

  • Patent number: 5708515
    Abstract: An image processing apparatus includes an imaging lens, an area image sensor having solid-state imaging elements arranged in a planar manner, and an imaging device for converting an image of an imaging object read by the area image sensor into image information. The imaging device is switchable between an electronic camera function mode and image scanner function mode. When the device is switched into the electronic camera function mode, the image information for one frame is outputted, whereas when the imaging device is switched into the image scanner function mode, the image information derived when an object to be read is manually scanned by the area image sensor in response to a moving amount of the manual scanning operation is outputted as continuous image information. Image information may thus be acquired over a wide range by employing a single image information processing apparatus.

  • Patent number: 5708662
    Abstract: A CPU enables an FM tuner, a tuning controller and an FM multiplex decoder, after which the CPU is disabled. The FM tuner, tuning controller and FM multiplex decoder receives frame data including emergency information transmitted from a broadcasting station. When a packet coincidence circuit determines that the received block is a specific block which may include emergency information, the FM multiplex decoder causes an emergency information determining circuit to determine if the associated packet contains emergency information. If this packet contains emergency information, the emergency information determining circuit sends an interrupt signal to the CPU to enable the CPU. The CPU then reproduces the emergency information in the received data and displays it on a display section.

    Abstract: To provide a machine composer capable of efficiently composing natural melodies with a simplified system configuration and without requiring complicated data processing: A melody material storage 10 stores a plurality of melody materials each represented by a plurality of note records. Each note record in a melody material contains data items of pitch and note type or function. Thus, pitches of the plurality of note records constitute an original pitch succession whereas note types of the records define an original note type succession. A note type of each note record represents a pitch function specified by musical background of the original pitch succession. A input device 20 enters musical background information (including for example keynote, scale and chord).
