He has made significant contributions to the field of technology, particularly in the area of arbitration systems and data coherence in processor caches. With a total of 3 patents to his name, Rodiger's work has had a lasting impact on the industry.
Latest Patents
Rodiger's latest patents include the "Look-ahead priority arbitration system and method." This invention presents an improved arbitration system for managing signals at multiple input nodes to output nodes, allowing each input node to access any output node. The system features a FIFO (first-in-first-out) input queue for each node, along with mechanisms for arbitrating the top of each queue to provide the necessary output. Additionally, it includes provisions for handling requests when the top of the input queue has no active requests.
Another significant patent is "Coherence control by data invalidation in selected processor caches." This patent describes a coherence directory and its operational methods for private processor caches within a multiple processor system. It effectively controls data coherence by providing cross-invalidate (XI) controls for the assignment of exclusive and public ownership to data units in processor caches. This innovation enhances data coherence efficiently, whether or not a shared second level (L2) cache is utilized.
