Design Of SCA Architecture Based On RTOS Communication Terminal

Real-time operating systems have been widely used in embedded fields such as defense,industrial automation and communications,and embedded systems are moving towards complexity,scale nd intelligent,with respect to functions,performance,power consumption,and cost.More requirements and constraints were put forward.How to strike a balance between different requirements and constraints is a challenge for embedded system design in the future.Platform design is one of the effective ways to address this challenge and balance the many requirements and constraints of embedded systems.Platform design is a system-level design method that includes both software platformization and hardware platformization.Its core is to emphasize the reusability and programmability of hardware and software to achieve flexibility for different applications.On the one hand,it emphasizes hard/software collaborative design to achieve design optimization.In response to these problems,this paper explores the SCA architecture design based on RTOS terminals.The main work is:Study the kernel structure,BSP structure,scheduling principle of different real-time operating systems,and explore and analyze the main scheduling functions.Improve the portability and sharing of components,and combine the SCA architecture and heterogeneous platform to design reconfigurable components of the signal data processing platform.Based on the advantages of loose coupling of component interfaces in SCA architecture,combined with the advantages of software reconfiguration technology,ion layer technology and message middleware,a design method of reusable software based on SCA architecture is proposed.Explore the development and portability of components such as Redis and Python in the real-time operating system platform,verify the portability of the components,and compare and analyze the results of the Linux operation.
