Predictive Sampling and Reconfigurable Technology Based Intelligent Memory-measurement System

摘要

Design ideas for the intelligent memory and measure system were presented in this paper. A CPLD, which is the core controller in the data acquisition system, controls the work of ADC, the process of the state machine, the memory and reading of data, the communication with a MCU and transceiver. The predictive sampling technology is proposed in the system for triggering the ADC to sample signal at appropriate time. Reconfigurable technology makes the system can adjust its sampling rate from 0 to 40Msps. The memory and restoring of data is elaborately designed. The experiment indicates the system with intelligence can work reliably and accurately.
