【摘要】 文章讨论了基于IntelPXA270微处理器的开发平台上使用TSC2101控制芯片完成音频控制系统的软硬件设计,以及在WindowsCE操作系统中的驱动程序的开发。在音频驱动程序设计中综合使用了DMA、双缓存区等技术以提高系统性能,满足音频实时性的要求,同时还保证音频数据的不丢失。更多还原

【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.更多还原
