Design And Realization Of EDSP Embedded Integrated Development Environment

At now, the development of embedded system changes with passing day, in our country, some embedded processors having full knowledge property right has been developed, such as Dragon Chip, Ark Chip. Research and development of the new type embedded system are becoming the emphases and hotspot. For the characteristics of embedded system, there are some special requirements to development, which are not only satisfied with the function of the products in different fields, but also guarantee the quality of products. Therefore, it must offer an efficient and convenient integrated development environment for embedded system development. Developers can use those tools to efficiently design embedded products that are needed by market.This paper mainly launches on the research actuality of domestic and foreign, and combines with series chip of EDSP218X, designs and realizes the EDSP integrated development environment. It's a full function, stable performance, and having full knowledge property right integrated development environment.By analyses of the popular system structure of domestic and foreign, it puts forward a full function, having currency and openness system structure of EDSP embedded system integrated development environment.It puts forward a method for distill object file debug information by analyses of ELF/DWARF object file format, designs a flexible data structure, and realizes the debug information distilled.Aimed at the series chip of EDSP218X's instruction set, designs and realizes the disassemble function of it.By analyses of the series of EDSP218X's instruction function, it puts forward an instruction set simulation method, and realized it. It introduces the basis function of debugger, puts forward the algorithm and realizes it.Last, it introduces the design of EDSP embedded system integrated development environment, and shows the correctness and efficiency by a example.
