摘要
将软件成分从硬件细节中分离 ,I/ O设备驱动程序在 DSP应用发展中起到了重要作用。它促进了软件重用、模块化设计、硬件和软件的谐调发展。本文为使用了 DSP/ BIOS 内核的时实 DSP应用程序中的流式 I/ O设备驱动程序定义了灵活的 API(application programminginterface)。本文实例运行在 TMS3 2 0 5 4 0 2 DSP初学者开发工具上。
I/O device drivers play an important role in digital signal processing(DSP) application development by separating the software components from hardware details.This promotes software reuse,modular design,and codevelopment of hardware and software.This note defines a flexible application programming interface(API) for streaming I/O device driver for use in real-time DSP application written with the DSP/BIOSⅡ real-time kernel.The Example included in the note runs on the Texas Instruments TMS3205402 DSP Starter Kit(DSK).
