| Embedded system is one of the top hot concept , it is also another hot spot in the development of today's electronical technology. Because it has successeding characters;the small volume, the strong performance, the low power consumption, the highly reliability and facing to industry application, it has been widely applied in many fields, such as military affairs , consuming electrony, internet communication , industrial controlling.Embedded system has enter into the SOC stage of hardware. Nowadays, embedded system designs based on SOC techonologyare primarily two methods: SOC based on ASIC (Application Specific Integrated Circuit), and SOPC (System on a Programmable Chip) based on Programmable Logic Chip. With the rapid development of Programmable Logic Chip in recent years, the advantage of SOC based on Programmable Logic Chip are also emerging quickly, smart design, perfect software develop flat, plentiful IPcore and so on, making SOC based on programmable Logic Chip get more and more widely apply.NIOS CPU (the NIOS adopted in this thesis is NIOSII ) is a kind of CPU which Altera cooperation designed specially for SOPC, which is brought to embedded system designer as the form of IP core, its characteristic which could be programmed brings more flexibility for design of embedded system, and it could also be said that it suggests a whole new idea for design of embedded system.This design choose EP1C12Q240C8, which is one of series of Cyclone, as system core, constitute an innate full hardware flat including: UART,FLASH, SDRAM and so on, completing debugging of the hardware flat, design of NIOS and transplant μC/OS (theμC/OS adopted in this thesis isμC/OS II) .This paper introduce the research, develop, design and realization course of the whole system flat in details .which divided into three part: Part one describesthe hardware design and design of PCB;Part two is about the design of NIOS by the software which is offered by Altera;Part three talks about the transplant of//C/OS... |
