Latest Patents

One of his latest patents is titled "System and method for performing conflict resolution and flow control in a multiprocessor system." This invention provides a system and method for managing requests from one or more requesters to one or more resources. The requests, which may be of multiple types, are prioritized using one or more threshold values. Each threshold value is associated with specific request types and defines the maximum number of requests that may be pending before the threshold is reached. When all thresholds are reached for predetermined request types, an indication is provided to re-issue those requests later. A priority scheme is implemented to ensure that re-issued requests systematically gain access to the shared resource, preventing starvation of any requester.

Another significant patent is "System and method for fault handling and recovery in a multi-processing system having hardware resources shared between multiple partitions." This invention addresses the issue of poisoning specific memory locations when a part of a multiprocessor system becomes faulty. It allows for the isolation of specific data owned by failing units, even in a shared memory area, while enabling continuous processing by non-failing units. A support processor is utilized to handle non-immediate problems and allows for the resetting of memory locations previously owned by failed units.
