Abstract (en)
[origin: WO9615484A2] 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.
