Crosstalk is one of the major problems in VLSI circuits of high-speed buses. To eliminate this problem, several types of coding techniques have been proposed in the literature. The paper aims at avoiding the opposite transition on any two adjacent wires. Sequential bit-stuffing algorithm and parallel bit-stuffing algorithm are studied. The problem in parallel bit-stuffing algorithm is that the code rates for even-numbered wires are significantly lower than those of odd-numbered wires. To solve the uneven rate problem, the paper considers parallel bit-stuffing algorithm with rate balancing, where padding of additional bits on odd-numbered wire with the help of 2 2 crossbar switch with bar state and cross state is done. By doing so, even-numbered code rate becomes equal to odd-numbered code rate, then code rates become balanced. Parallel bit-stuffing algorithm with rate balancing not only achieves higher coding rate but also lowers power consumption.
