Patent
System and method for preserving message order while employing both programmed I/O and DMA operations
TL;DR: In this paper, the first node's network interface packetizes the sequence of PIO and DMA commands to generate an ordered stream of data transfer packets whose order corresponds to the predefined message component order.
Patent
System for context-dependent name resolution
TL;DR: In this paper, a context-dependent multiply binding name resolution system is proposed, which resolves requests to a given service or domain name to the appropriate IP address based on a combination of one or more predetermined criteria, including: information about the sender (e.g. geographical location, specific requester identity, etc.).
Patent
Transaction activation processor for controlling memory transaction processing in a packet switched cache coherent multiprocessor system
Zahir Ebrahim,Satyanarayana Nishtala,William C. Van Loo,Kevin Normoyle,Paul N. Loewenstein,Louis F. Coffin +5 more
TL;DR: In this article, the system controller includes transaction activation logic for activating each memory transaction request when it meets predefined activation criteria, and for blocking each said transaction request until the predefined activating criteria are met.
Patent
Method and apparatus for implementing hardware protection domains in a system with no memory management unit (MMU)
TL;DR: In this article, a low overhead, efficient, and simple protection check circuit is inserted into a data path between a master requester and a target resource such as a memory or input/output device.
Patent
A fast, dual ported cache controller for data processors in a packet switched cache coherent multiprocessor system
TL;DR: In this article, the cache controller has two modes of operation, including a first standard mode of operation in which read/write access to the cache memory is preceded by generation of the hit/miss signal by the comparator, and a second accelerated mode of operating without waiting for the comparators to process the access request's address value.
