Abstract:

This paper introduces implementation of an oversampling technology based on ARM Cortex-M3 kernel.Experiment indicates that oversampling technology can achieve the same sampling effect without external ADC device.The combination of Cortex-M3 kernel and oversampling technology not only reduces the cost,but also improves system's operating rate,reliability and stability.

Key words: Cortex-M3;oversampling;analog to digital converter;resolution
