Title: David A Webb: Innovator in Processor Technologies

Introduction

David A Webb is a notable inventor based in Groton, MA (US). He has made significant contributions to the field of computing, particularly in processor technologies. With a total of 3 patents, Webb's work focuses on enhancing communication and cache management in many-core processors.

Latest Patents

Webb's latest patents include groundbreaking technologies for automatic processor core association management and communication using direct data placement in private caches. This innovation involves multiple computing nodes that communicate over a network. Each node features a many-core processor equipped with an integrated host fabric interface (HFI) that maintains an association table (AT). Upon receiving a message from a remote device, the HFI checks the AT for an entry linking message parameters to a destination processor core. If a match is found, the HFI directs a data transfer agent (DTA) of the destination core to receive the message data, which may be stored in the core's private cache. The parameters can include a destination process identifier or a virtual memory address range. The HFI can also automatically update the AT based on communication operations generated by the processor cores' software.

Another significant patent involves hardware apparatuses and methods to control cache line coherence. This patent describes a hardware processor that includes a first processor core with a cache for storing a cache line, alongside a second set of processor cores, each with a cache for holding a copy of the cache line. The cache coherence logic aggregates acknowledgment messages from the second set of processor cores in response to requests from the first processor core to modify the cache line copies. This consolidated acknowledgment is then sent back to the first processor core.
