摘要
Abstract
When implementing tasks based on the traditional DSP6713 processor,the control program structure primarily adopts a foreground-background architecture.While this approach suffices for simple application processing scenarios,it fails to meet requirements in scenarios involving"managing multi-port data reception and data processing tasks".Although TI officially provides the DSP BIOS real-time operating system,its closed-source nature imposes certain limitations on usage.Additionally,the uncertainty in the register push/pop sequence order during the execution of interrupt service routines on the DSP6713 processor creates significant challenges for porting common RTOS systems.To address these issues,this paper proposes a context switching method specifically designed for the DSP6713 processor.Taking the domestically developed RT-Thread operating system as an example,we demonstrate its successful porting and showcase multi-task application scenarios.This method achieves an optimal balance between economic benefits and processor efficiency without requiring hardware upgrades,offering a novel solution for platform applications and upgrade transformations centered on DSP6713 processors.关键词
