一种对称式双处理器模块的设计与实现

Design and Implementation of a Module with Symmetrical Dual-processor

随着嵌入式机载计算机处理任务的增加,系统对数据处理功能模块性能提出了很高的要求,采用对称式双处理器是提高功能模块数据处理能力简单而有效的方法。介绍了对称式双处理器结构特点,提出了模块组成结构以及关键电路的设计实现,给出了模块测试性设计。

Because of the increasing of tasks in the embedded airborne computer,the system has proposed a very high demand for the performance of the data processing function module.The usage of symmetrical dual-processor is a simple and effective method to enhance the data processing performance of the module.The paper describes the structural characteristics of symmetrical dual-processor,and then presents a module structure as well as the design and implementation of the key circuit.The paper also proposes a design for the testability of the module at last.
