Location Information Acquisition in Real Time Scheme’s Design and Application in High Response and High Precision Servo Based on CPLD
摘要
Abstract
Two sets of position detection scheme were designed. One connects CPLD, DSP and decoding chip with the method of independent bus. It could real-time update location information. The other connects CPLD, DSP and decoding chip with the method of shared bus. It only read location information when it need. Both schemes’ hardware platform, design thought, software flow diagram were proposed. Its principle was analyzed. The position information was detected based on these two schemes. According to these experiments, these two solutions all could read location information accurately with high precision, and be used in high power driving situations. Comparing with independent bus solution, Reuse bus solution had the faster response speed.关键词
