Abstract:
Objective To develop a lossless compression algorithm applied on the MCU.Methods Direct difference data compression and 2-4-8 three-word-length coding data compression based on the first order difference were developed.Statistics on the results of the first order difference of ECG data in the MIT_BIH ECG database resulted in an optimal three-word-length code table.Results Direct difference data compression ratio was lower than 2,and three-word-length data compression ratio was around 3.Conclusion There are both advantages and disadvantages in two types of lossless data compression,but three-word-length data compression is superior to direct difference data compression.[Chinese Medical Equipment Journal,2008,29(2):24-27]
