摘要
针对广泛使用的DSP处理器,分析TI公司实时操作系统DSP/BIOS的特点,论述DSP多任务实时操作系统架构。基于DSP/BIOS完成任务创建与堆栈检测、中断管理、时钟管理、多任务调度策略及任务间通讯等内核关键部分的设计,实现一个具有基本功能的DSP多任务实时操作系统内核。并给出所设计的内核软件在TI的DSP TMS320C6655上的应用实例,通过实验验证内核的一些关键功能(定时器、任务调度策略)。所设计的多任务操作系统内核,架构简洁,实时性强,便于进行二次开发。
In view of the widespread use of DSP processor, Analysis of the characteristics of TI company real-time operating system DSP/BIOS,DSP real-time multitasking operating system architecture is also discussed. The key part of the kernel design is based on DSP/BIOS to complete the task to create and stack detection, interrupt management, clock management, task scheduling strategy and intertask communication.All of the implement a basic function of DSP real-time multitasking operating system kernel. the design of kernel software is used on DSP TMS320C6655 application and through the experiment verify the kernel' s some key function(timer, task scheduling strategy). The designed multitasking operating system kernel architecture is simple, it has strong real-time performance,and is convenient for secondary develop-ment.
