The Application Of Software On DSP In Process Control Field

As the most optimum way to resolve software crisis, software reuse technology has got the general attention. It is estimated that by the 2003 seventy percent of the new application program will be construed by building components. Most of them, for example software component and application program structure, quicken the product development rate and improve the ability to meet the company's adapting.Software reuse based on software component is the main form of product reuse. Software component technology is the focus in the field of reuse study and is considered to be the key factor to fulfill software reuse. At the same time, with the appearance of object- oriented technology, it has provided the technology support for the fulfillment of the software component. At the past we adopted the structure analysis to develop software system, so most of the unsuccessful cases can not satisfy the client's actual need because of the long period. But the development technology based on the component can construct a new application rapidly by reusing the component available or developing a little new components as the computer hardware engineers constructing a new computer with the IC. Software component technology has been main stream of the actual software development technology.At the moment, the single chip micyoco system has not satisfied the user in many fields because we have more strict demands on the characters in real time, computing precise and data operation rate of the measure control system. DSP has replaced the single chip micyoco system becoming the hotspot technology because of its high operation rate and precision.This paper describes the application of TMS320C2812 based on SHDSP2003 system. It is introduced the design and development of basic module, communication module and PID controller.The updated SHDSP2003 system has passed debugging and will be usedin the new project. It is proved by the test to be feasible, reliable and universal. This is the profitable experiment to develop the software component in the embedded high real time operation system.
