Based On Arm Embedded Software Interrupt System Simulation

With the rapid development of mobile Internet, embedded systems have beenwidely used in a variety of intelligent terminals. A simple, fast, safe, reliable hardwaresimulator for embedded system software developer plays an important role. It not onlycan promote the software and hardware synchronization, increase developmentefficiency, shorten the development cycle, but also can reduce software developmentcosts. By the way, the software developers can focus on software development itself,without the need to consider the complexity of the hardware structure. Interrupt controlsystem plays a role as a bridge between the peripherals and the processor in ARM-basedembedded hardware simulation systems, which is more effective to improve theefficiency of the system. As a separate hardware component simulators to analysis anddesign is extremely necessary.According to the nuclear high base project, we need to develop a scalable softwaresimulation platform, the platform contains processor, bus, memory, and peripherals, andother modules. The interrupt controller as an important component of the simulationplatform, we need to research and analysis of embedded interrupt controller softwaresimulation technology.This thesis research interrupt control system of ARM-basedembedded system software simulation, including the embedded ARM processorinterrupt control system hardware unit and the software simulator theory. This thesisintroduces the simulation.Apsim overall framework and instruction set simulator relatedtechnology. According to the embedded ARM processor interrupt control systemsresearch, the use of object-oriented and the theory of finite automata method to extractabstract the hardware interrupt controller component simulator uniform interface. Thisis a general principle of the interface, which can be built out of our common interruptcontroller software simulation framework. We only need to perceive interrupt controllerlogic to adjust the interface. Meanwhile, the framework has a strong commonality andscalability.According to specific s3c2410embedded development board hardware interruptcontrol system works, the use of finite automaton technologies for the entire migration process-related create effective modeling. By the interrupt controller hardware works,we use a unified interface to complete the simulation module s3c2410develop boardinterrupt control system simulation software. We use the debugging, tracking, testingand related technologies to verify the hardware interrupt controller interface and oursoftware simulation accuracy and availability. After a lot of experimental proof, basedon the interrupt controller simulation interface to build the s3c2410interrupt controllersystem software simulation is correct, and available.
