Coupling-Driven Signal Encoding Scheme for Low-Power Interface Design

Coupling effects between on-chip interconnects must be addressed in ultra deep submicron VLSI and system-on-a-chip (SoC) designs. A new low-power bus encoding scheme is proposed to minimize coupled switchings which dominate the on-chip bus power consumption. The coupling-driven bus invert method use slim encoder and decoder architecture to minimize the hardware overhead. Experimental results indicate that our encoding methods save effective switchings as much as 30% in an 8-bit bus with one-cycle redundancy.
