Lower Memory Utilization for Digital Data Acquisition and Transmission Systems.
Zaini Abdul Halim · 2008
In most digital data acquisition systems, a digital sampler with high sampling rate may be employed to record signals before being analyzed by an embedded processor or stored into a memory buffer. Due to high sampling rate, the signals are recorded as redundant bits of ‘1’s or ‘0’s, which inadvertently increases the memory storage utilization. The data representation technique and memory cell design steps proposed in this paper are aimed at providing compression to the redundant binary bits. Specific purpose applications where the technique can be employed are digital logic analyzers, universal remote controls, and data loggers.
