Embedded quality analysis platform based on HPI technology

The embedded quality data acquisition and analysis platform which meets the demand of field real-time quality control against more and more complicated quality control in inter-enterprise is presented in this paper. With HPI technology and regionalization of HPI memory mapping strategy first being adopted in this platform and the accomplishment of HPI driver under Windows CE.net, seamless connection between ARM and DSP is well implemented. Based on event-driven strategy for field quality data real-time acquisition and chain table priority strategy for multi-task scheduling, real-time mixture quality data acquisition and analysis on DSP and the friendly human-interface for real-time display and network data exchange on ARM are realized through HPI technology. System platform for field data dynamic processing and analysis is implemented and improved accordingly.
