Abstract
A data bus on an integrated circuit includes a series of selectors arranged in a ring, each selector having an output terminal, an enable terminal, a ring input terminal, and a data input terminal. The ring input terminal receives data from another selector in the ring. The data input terminal receives data from a data source. The output terminal supplies data to the ring input terminal of a next selector in the ring. The enable terminal receives enable signals from a data source. A selector either propagates the signal on its ring input terminal or a data signal on its data input terminal to the next selector.
