The online analytical instrument platform based in SOPC can complete the basic functions from data acquisition to display. The data validation, the link of platform and network, and data transmission are facilitated by adding the communication with the host compute. So the information management of the host computer is realized in nonlinear verification and TCP / IP communication.And the data processing ability of intelligence platform of online analytical instrument based on the SOPC is verified.
According to the automatic control requirements of heating community, a heating control system is designed with the host computer, PLC and kinds of temperature, level, pressure sensors. Through WinCC confi guration of Siemens, the confi guration screen and monitoring procedures are designed. So the fi eld test of temperature, pressure, fl ow of community heating system is conducted, and the heating effect is improved.
In this paper, we researched the hardware- decoding based on DXVA and OpenCL which using a encoded image inH.264 as an example. We designed a hardware decoding process using DXVA2 and the OpenCL API, and we got the testing data toverify the possible solutions.
