Designment Of The Extensible Embedded System Based On ARM And CPLD

After the 1990s,with the development of information industry and INTERNET, embeddedsystem technology abstained almost unlimited space for development.The purpose of my project is to arise and design an extensible embedded application systemplatform based on ARM and CPLD. Hardware of the system is developed with the ALTIUMDESIGNER 6.0 EDA software. Design regulation on high speed PCB is adopted to ensure stabilityof the system. With the BLUETOOTH module, the system provides the customers with an perfectapplication solution for most possible usages, the specific works of the research topic is as below:1. An integrated platform for multifunctional embedded system is designed with LPC2292embedded processor. Based on this platform, many embedded applications can be easily realizedwithout any modification on hardware, such as Ethernet gateway,CAN gateway,industryapplications and so on. Within the designment practice, the rules and the method to design anembedded system hardware platform are successfully summarized.2. PCI bridge firmware is successfully designed and tested, the PCI devices is successfully attachedon the ARM hardware platform, so the communication problem existing between ARM and PCIslave devices is perfectly solved.3. Designment of the PCI test card based on AT89C51 single chip machine is completed, the testcard can effectly test the PCI communication functions of the system hardware platform and by thisway to ensure normality and stability of the system when operating. The system can also beadopted as an experiment platform to cultivate the concerned students in university.
