This paper presents a design of an asynchronous peer-to- peer half-duplexjfull-duplex-selectable data-transfer system on-chip interconnected. The data-transfer method between channels is based on a 1- phase signaling scheme realized by using multiple-valued current-mode (MVCM) circuits and encoding, which performs high-speed communication. A data transmission is selectable by adding a mode-detection circuit that observes data-transmission modes; full-duplex, half-duplex and standby modes. Especially, since current sources are completely cut off during the standby mode, the power dissipation can be greatly reduced. Moreover, both half-duplex and full-duplex communication can be realized by sharing a common circuit except a signal-level conversion circuit. The proposed interface is implemented using 0.18-pm CMOS, and its performance improvement is discussed in comparison with those of the other ordinary asynchronous methods.
