Ring generators are high-performance linear feedback shift registers capable of handling pseudorandom and deterministic binary sequences. They outperform all traditional solutions by providing an unprecedented speed of operations and a layout-friendly structure. In particular, these devices feature a very shallow digital logic, significantly reduced internal fan-outs, and simplified circuit layout and routing, as compared to many earlier schemes based on linear finite state machines, all implementing the same characteristic polynomial. Consequently, they can serve in the same role as many of their predecessors without compromising the quality of advanced nanometer designs.
