Design And Realization Of Input/Output System

With rapid development of the Aviotronics, centralized control and integrated display technology are larged used in the Avionics System of nowadays advanced avions. As the core of Avionics System's control system and management, Integrated Display Processor is responsible for signals handling on all kinds of interfaces, and implements all types of serial data communication,data collection and output, the quality and technology used of this Integrated Display Processor stands for the development of Aviotronics. In Integrated Display Processor, it introduces more input/output interface applications, whose reliability,integrated display capability become the key factors in system development.Firstly, this thesis has a deep analysis and system design according to the requirement for input/output interface processing module from Integrate Display Processor. After the detailed research and discussion to all communication protocols, 2 kinds of solutions are brought forward. Finally the solution based on MPC860 is choosed which is regarded to the most reasonable and efficient solution with maturity and new technology.Next, this thesis describes the interface,protocol and function in detail, which provides the strong viewpoints for solution in theory.Finally, it puts more emphasis on the study and discussion on system design,hardware design and software design for this input/ouput interface processing module, and it also involves module dubug and test result, including debug environment, debug steps,test environment and test program. From the test results, we can draw a conclusion that this solution reaches to the proformance requirement from Integrated Display Processor on some aspects, such as reliability,measurability,system expansibility. In particular, it extremely improves the system performance of Integrated Display Processor, enhances the quality of avions.
