嵌入式系统的应用越来越广泛。DSP是针对实时信号处理而设计的,非常适合应用于嵌入式实施系统。DSP在嵌入式系统中除了扮演微处理器的角色之外,还兼有控制器的功能。DSP对外部数据采集的操作是整个系统的一部分,为了更有效地使用DSP的资源,就要用到BIOS的实时多任务功能来实现多任务的调度和切换。多任务处理器能够最大程度地利用资源,并且也提供应用程序的模块化构造。使用了多任务处理,应用程序通常更容易设计和维护。
Embedded systems are used more and more widely. DSP is designed for real-time signal processing and is ideally suited for embedded implementation systems. In addition to playing the role of microprocessor in embedded systems, DSP also has the function of a controller. DSP external data acquisition operation is part of the entire system, in order to more effectively use the DSP resources, it is necessary to use the BIOS’s real-time multi-task function to achieve multi-task scheduling and switching. Multitasking maximizes resource utilization and also provides a modular construction of the application. With multitasking, the application is usually easier to design and maintain.
