Design and Implementation of a High Efficient DDR SDRAM Controller Applied in TOF-MS
Qian Li, Ming Wang, Yang Yu · 2015
Owing to large capacity and high speed, DDR SDRAM has been widely used in the data acquisition system of time-of-flight mass spectrometer (TOF-MS) which can detect and analyze biological and chemical macromolecule precisely.Due to the particularity of the requirement of large amounts of data accumulation in TOF-MS signal processing, the time cannot be efficiently used during reading and writing in traditional design of DDR SDRAM controller.This paper presents a new strategy of reading and writing, increasing the efficiency of data processing greatly and finally a DDR SDRAM controller has been implemented.Software simulation and hardware implementation prove the correctness and feasibility of this design and the efficiency of reading and writing reach up to 93.6%.
