Comparison and analysis of Quotient Remainder Compression-algorithms for automotives

Today, electronically controlled modules or electronic control units (ECUs) are part of any automobile. These are deployed for managing critical and not so critical operations in automotives. Thus, a lot of communication occurs between these ECUs. Use of Data Reduction (DR) algorithm reduces the amount of data transferred in a given time thus improving the performance of the communication between the ECUs. Supriya Kelkar and Raj Kamal have proposed and implemented Quotient Remainder Compression (QRC) algorithm for Controller Area Network [1] and showed the improvement in the range for the parameters compared to the earlier Enhanced Data Reduction (EDR) algorithm [2]. In this paper, authors of [1] have developed two more versions of QRC algorithm. Here, all the three versions of QRC algorithm are compared and their merits and demerits are stated.
