| Abstract: | This paper introduces application of CPLD on high-precision micro-distance and flux sensor measurement system on the basis of ultrasonic wave theory . High-speed, complex programmable logic device CPLD technique is used. High-speed double-port RAM, control sampling time sequence logic, CPU interfaces and bus circuit are implemented in CPLD. Sampling speed is up to 80MHz, sampling depth is 1K-byte, and CPLD can fulfill the requirement of the software arithmetic to sampling. What's more, it can on-line upgrade, greatly improves whole performance of system. |
