Gaining Predictability and Noise Immunity in Global Interconnects

We present a bundled data communication scheme that is robust to crosstalk effects, and to manufacturing and environmental variations. Unlike a data bus, where each receiver always connects to all data lines from the sender, we consider the case where each receiver can have a subset of all data lines routed to it. Such generalization can be used for a bundled data communication method applicable to both local and global communication. It can be used to make a clock unnecessary in a design. It also leads to a new routing problem for which we present an algorithm based on MRSA tree construction to solve it.
