摘要： Sound source data is constituted by a 14-byte sound data area SA consisting of 28 samples of 4-bit adaptive differential PCM data and a sound parameter area PA consisting of loop information LP, filter information FL and a shift amount RA.In encoding the sound source data, a CD-ROM XA encoder may be employed.4-bit ADPCM data is decoded by a BRR decoder 53, pitch-converted by a pitch conversion unit 54, and then processed with envelope transform by an envelope generator 58. After that, sound outputs of left and right channels outputted with the sound volume adjusted by volumes 60L, 60R, and 16-bit PCM data with the sound volume adjusted by a mixing volume 65, are added by an adder 62. Further, the sound data from the mixing volume 65, or an addition output produced by adding the sound data from the mixing volume 65 with the sound data from the volumes 60L, 60R, is reverberated by a reverberation processor 68. The sound data with the sound volume adjusted by a reverberation volume 69 and the sound data from the adder 62 are added.The sound source data and the real sound data can be easily mixed in a single circuit.

摘要： A real time texture mapping method produces an image of an object having a surface that has dynamically changing texture by using image data and moving image texture pattern data. The image data is stored in a drawing area of an image memory, and the moving image texture pattern data is stored frame-by-frame in a texture area of the image memory. The moving image texture pattern data stored in the texture area is mapped a frame per vertical display period onto the surface of the object which is represented in the image data stored in the drawing area. The new two-dimensional image data having the texture pattern data mapped on the surface of the object is used as a current image frame for display. The new image data having the texture pattern data mapped on the surface of the object may be stored in the texture area of the image memory, and used as a new texture pattern to map onto a second object stored in the drawing area for a next image frame to be displayed. A video game apparatus implementing this method includes the image memory having a display area as well as the texture area and drawing area. The display area stores image data of the current image frame for display. The drawing and display areas have interchangeable functions.

摘要： An apparatus for generating the interrupt information includes an addressing device for generating the specified address information for specifying the desired information stored in a memory device, a readout address generating device for generating the readout address information of the desired information stored in the memory device, and a comparator device for comparing the specified address information from the addressing device and the readout address information from the readout address generating device and for generating the interrupt information in case of coincidence of the specified address information and the readout address information and supplying the interrupt information to a central processing unit. Since the interrupt data is supplied to the central processing unit at the playback timing of the desired sound source data, reproduction of the sound source data can be detected, so that it is unnecessary for the central processing unit to poll the address of the sound source data at all time and hence the load imposed on the central processing unit may be correspondingly decreased.

摘要： An apparatus for processing the speech information includes a first execution device and a second execution device for executing operations at respective different execution cycles, and a first memory unit for reading and recording the speech information. The first execution device and the second execution device exploit the first memory unit in common for processing the speech information. The processing apparatus further includes a second memory unit for storage of the speech information from the first execution device or the speech information read out from the first memory unit. The first execution device records the speech information on or reads the speech information from the second memory unit during the execution cycle of the first execution device. The second execution device accesses the first memory unit during the execution cycle of the second execution device for outputting the speech information to outside. The speech information recorded in the second memory unit is read out and recorded in the first memory unit or the speech information recorded in the first memory unit is read out recorded in the second memory unit during the time of not accessing the first memory unit. The data transfer between first execution device and the second memory can be performed during the execution cycle of the first execution device, while that between the second memory unit and the first memory unit can be performed during the execution cycle of the second execution device, so that it is possible for the first execution device to perform data transfer independently, such that sound source data can be transferred at a higher speed by employing a high-speed device as the first execution device.

摘要： A method and apparatus for generating images wherein access to a main memory is minimized during a translation of an image of a 3D object or the like on a display screen to increase the speed of the translation process. A string of draw commands for drawing an image is preceded by an offset draw command which indicates offset values for the coordinates of the vertices of the image, and the image is translated on the display screen in accordance with the offset draw command. A header portion of each of the offset draw command and the draw commands that constitute the draw command string includes data indicating the address on the main memory of the next draw command to be executed. The image generation apparatus includes a frame buffer in which an image is drawn, a CPU for generating a string of draw commands to draw the image and an offset draw command indicating offset values for the coordinates of the vertices of the image, a main memory for storing the string of draw commands and offset draw command generated by the CPU, and a drawing device portion for executing the string of draw commands and offset draw command from the main memory to draw a translated image on the frame buffer.
