Optimizing Architecture of DSRC Device By Using Component Reuse

B Mounica, N.G.N Prasad


Dedicated short-range communication (DSRC) is an emerging technique to push the intelligent transportation system into our daily life. The DSRC standards generally adopt FM0 and Manchester codes to reach dc-balance, enhancing the signal reliability. Nevertheless, the coding-diversity between the FM0 and Manchester codes seriously limits the potential to design a fully reused VLSI architecture for both. In this paper, the similarity-oriented logic simplification (SOLS) technique is proposed to overcome this limitation. The SOLS technique improves the hardware utilization rate from 57.14% to 100% for both FM0 and Manchester encodings. Differential Manchester can improve noise immunity over Manchester. Area improvement for FM0/Differential Manchester has been increased to 47% from 16% of Manchester
