專用短程通訊(DSRC)是一新興的通訊協定,藉此來達到現代汽車工業的進步。DSRC協定通常使用FM0及Manchester編碼來達到直流平衡,藉此可以增加訊號傳輸的可靠度。然而,不平衡的計算負載(unbalance computation-load)使得FM0和Manchester編碼器的硬體共用效率變低。 在本專利中,布林函數簡化的方法來提升硬體共用性的方法被提出來解決此問題。由布林函數簡化技巧,硬體共用率由原本的55%提升至100%。這套硬體架構由 TSMC 0.18-um 1P6M CMOS technology來實現。它的gate count為39.58,功率消耗120uW@500MHz。編碼的能力被提升到500Mbps,並且可以支援歐洲、美國、日本的DSRC標準。 The Dedicated Short-Range Communication (DSRC) is an emerging standard to push the vehicular communication into modern automotive industry. The DSRC standards generally apply FM0 and Manchester to reach DC-Balance that enhances the signal reliability. However, the unbalance computation-load between FM0 and Manchester makes their VLSI architecture with poor hardware utilization. In this patent, the Boolean simplification technique is proposed to overcome this problem. The Boolean simplification technique enhances the hardware utilization, and provides the balance-type architecture for FM0/Manchester encoding. With Boolean simplification technique, the hardware utilization rate is improved from 55% to 100%. This work is realized by 0.18-um 1P6M CMOS technology. The gate count is 39.58, and the power consumption is 120uW@500MHz. The encoding capability is up to 500Mbps that can fully support the DSRC standards of Europe, America and Japan.
