| Abstract: | The thesis introduces the software and hardware implementation of audio control system using TSC2101 controller based on Intel PXA270 microprocessor development platform. And its device driver for Windows CE embedded operating system is designed. Many techniques have been applied in the design of the audio driver, such as DMA, double- buffer, and so on, to improve the func- tion of the system, realize realtime processing, and meanwhile ensure that the audio data will not be lost. |
