More Information
Summary:A monolithic integrated circuit for providing enhanced audio performance in personal computers is disclosed. The monolithic circuit includes a wavetable synthesizer; a full function stereo coding and decoding circuit (CODEC) including analog-to-digital and digital-to-analog data conversion; data compression, and mixing and muxing of analog signals; a local memory control module for interfacing with external memory; a game-MIDI port module; a system bus interface; and a control module for compatibility and circuit control functions. Un circuit intégré monolithique, qui procure des caractéristiques audio améliorées aux ordinateurs personnels, comprend un synthétiseur à table de formes d'ondes, un circuit de codage et de décodage stéréo (CODEC) pour toutes fonctions y compris des conversions de donnés analogiques/numériques et numériques/analogiques, et il permet la compression de données et le mélange et le multiplexage de signaux analogiques et il comprend un module de commande de mémoire locale qui s'interface avec une mémoire externe, un module à port pour jeux à la norme MIDI, une interface de bus système, et un module de commande régissant des fonctions de compatibilité et de commande de circuit.
