Development And Application Of TPOS Embeded Platform

Chips have widely become a part of people's life including rest, study and work. At the same time the development of embedded system progress rapidly. All kinds of embedded systems come forth. There are more and more complex functions and more requirements of hardware. The competition is becoming more serious between different competitors. So to design a new platform with low hardware requirement and development cost will bring better competitive position. The requirement in different environments is particular, such as data collection system of electricity grid. It needn't most OS operation efficiency, but need highest data protect and system stabilization. So the cost will be seriously reduced if we can give a platform which is lowest hardware requirement and sufficient to meet the requirements.This article will discuss how to design a software embedded platform that needs lowest hardware and software development cost. At the same time this platform must has maturity functions and the mostly reliable data protection. To let this embedded platform can be used in several target environments which are not too much complex. To develop real products based on this platform at the end.This article will discuss the basic platform at first. To choice platform characters needed and build up the basic software structure from the functions of different OS characters, such as time efficiency and space efficiency. Memory management is a key point for TPOS platform. The efficiency and stability of memory management will seriously affect the usability, maintainability and secondary development difficulty of the whole platform.If a platform can support more Peripherals, it will be easier used on more environments. So to choose several peripherals widely used to support, and develop appropriate driver for them including COM, USB, I2C and GPRS based on the COM, and PPP/UDP protocol stack for GPRS. File system is an important part of OS. The security of the file system directly determines the safety of data. The target application environment needs an absolute safe file system, so give a special file system based on NOR flash which gives some appropriative arithmetic focus on flash hardware protection, the data safety and IO efficiency.At last this article will talk about the real products based on TPOS. New characters and related arithmetic will be introduced.
