Title: Innovations of Donald L. Smith
Introduction
Donald L. Smith is a notable inventor based in Bedford, MA (US). He has made significant contributions to the field of multiprocessor systems, holding a total of four patents. His work focuses on enhancing the efficiency and performance of system buses in computing environments.
Latest Patents
Among his latest patents is the "Minimum contention processor and system bus system." This invention describes a multiprocessor system that includes multiple central subsystem (CSS) units, memory units, and input/output units connected to a system bus. The system bus facilitates the transfer of requests between units based on a priority defined by a distributed bus priority network. Additionally, a private bus (P bus) connects all CSS and memory units for high-speed block data transfers. The design allows for efficient bus access by generating transfer requests only when both the system bus and P bus are idle, thereby eliminating contention.
Another significant patent is the "Method and apparatus for a high performance round robin distributed bus." This invention also involves a multiprocessor system with identical CSS units and memory subsystems. It features cycle stealer logic circuits that grant bus cycles on a round-robin basis, ensuring that high-priority requests are prioritized while maintaining system efficiency.
