Abstract
A system and method for efficiently transporting data in a computing system are contemplated. In various embodiments, a computing system includes a source, a destination and multiple lanes between them for transporting data. Multiple receivers in the destination has a respective termination resistor connected to a single integrating capacitor, which provides a reference voltage to the multiple receivers. The receivers reconstruct the received data by comparing the corresponding input signals to the reference voltage. The source includes a table storing code words. The source maps a generated data word to a code word, which is sent to the destination. The destination maps the received code word to the data word. The values of the code words are selected to maintain a nearly same number of Boolean ones on the multiple lanes over time as a number of Boolean zeroes.
