摘要： PURPOSE:To transfer blocks at a high speed by using a means which extracts prescribed continuous bits out of the data to be transferred and produces 1-word data. CONSTITUTION:The source data SD of a transfer destination which is read out of a VRAM for each byte is inputted to a rotator 16 via a latch 11 and a selector 8 to be rotated in response to the bit address of the transfer destination and temporarily latched by an old data latch 17. Then the following read bytes are also rotated by prescribed rotational frequencies and synthesized by a phase mask logic together with the contents of the latch 17. The SD subjected to synthesis is inputted to a mask logic circuit via a logic arithmetic circuit 12 together with the head byte of the transfer destination to be synthesized in accordance with the contents of a mask register MASKO for the head byte of the transfer destination and outputted for each byte to a VRAM of the transferee.

摘要： PURPOSE:To directly take a synchronization according to a synchronizing signal extracted from an external video signal by presetting a counter for instructing horizontal and vertical positions to a preset value when an external synchronizing signal is supplied. CONSTITUTION:A picture processor 1 reads picture data (character code) in a VRAM3 under the control of a CPU2 and displays on a CRT display deice 5 based on the read data. the VRAM3 is suitably made access from the picture processor 1 or the CPU2 according to the switching processing of a multiplexer 4. A character generator 7 outputs dot data constituting a character pattern based on the character code supplied from the VRAM3 and a raster address RA supplied from the picture processor 1. In the picture processor 1, the counter for instructing the horizontal and vertical positions is disposed, and preset by the external synchronizing signal to decide the raster address.

摘要： PURPOSE: To finely control the sound from an object to reduce the burden to a host system by controlling the sound emitted from each polygon in accordance with the position and the direction of the polygon and an object table. CONSTITUTION: Three-dimensional coordinate values in the view coordinate system of apexes, the display color, and sound information such as the tone color, the tone quality, the sound pitch, and the sound volume of the emitted sound are stored in an object table 2 with respect to each of polygons constituting objects in three-dimensional CG(computer graphics). A sound source processing part 4 obtains the position of a virtual sound source and the direction of each polygon based on coordinate values of apexes of the polygon in the object table 2, and the sound designated by sound information is emitted through a sounding device 6 so that it is emitted from the obtained sound source position toward the polygon. In this case, the amplitude of the sound is controlled in accordance with the area of the polygon on the display screen of a display device 5 to emit the sound according with the direction of the polygon.

摘要： PURPOSE: To reduce the effect caused by a difference from an output characteristic and the position of a sounder or the like. CONSTITUTION: An audio output signal outputted from a sound source equipment 1 is subjected to electroacoustic transducing by a sounder 2 to provide a prescribed sound in the acoustic equipment, the sound source equipment 1 is provided with an attribute table 16 in which attribute information such as the impedance, frequency characteristic, phase characteristic and position or the like is stored. The sound source equipment 1 references the attribute information stored in the attribute table 16, so controls the audio output signal fed to the sounder 2 so as not to be dependent on the output characteristic of the sounder 2.
