US07926035B2 Testing multi-thread software using prioritized context switch limits
Testing multithreaded application programs for errors can be carried out in an efficient and productive manner at least in part by prioritizing thread schedules based on numbers of context switches between threads therein. In particular, each thread schedule in a multithreaded application program can be prioritized based on whether a given thread schedule has the same as or less than some maximum value. A model checker module can then iteratively execute thread schedules that fit within a given context switch maximum value, or a progressively higher value up to some limit. In one implementation, for example, the model checker module executes all thread schedules that have zero preempting context switches, then all thread schedules that have only one preempting context switch, etc. Most errors in an application program can be identified by executing only those thread schedule with relatively few preempting context switches.

US07926021B2 Insertion of error detection circuits based on error propagation within integrated circuits
A method of selecting where error detection circuits should be placed within an integrated circuit uses simulation of a reference and test design with errors injected into the test design and then fan out analysis performed upon those injected errors to identify error propagation characteristics. Thus, registers at which propagated errors are highly likely to manifest themselves or which protect key architectural state, or which protect state not otherwise protected can be identified and so an efficient deployment of error detection mechanisms achieved. Within an integrated circuit output signals from inactive circuit elements may be subject to isolation gating in dependence upon a detected current state of the integrated circuit. Thus, inactive circuit elements in which soft errors occur have inappropriate output signals gated from reaching the rest of the integrated circuit and thus reducing erroneous operation.

And finally, a set of logical consequences of the logic formula is produced and each logical consequence is enumerated as an assertion.
US07926019B1 Common clock path pessimism analysis for circuit designs using clock tree networks
Method, computer program and system to perform timing analysis of designs containing clock networks by eliminating Common Clock Path Pessimism. The method includes transforming a clock network into a clock tree that includes nodes with different clock signal arrival times and leaf nodes representing source and destination registers.

The creation of CCPP groups enables analysis time reduction because only one timing calculation is required for the CCPP group instead of having to perform the analysis for each possible pair of registers. The method eliminates CCPP for each CCPP group and then displays the results.

Remote peripherals appear to the operating system to be located on the local processor's own peripheral bus. A processor, DRAM, and north bridge connect to a south bridge interconnect fabric chip that has a virtual Ethernet controller and a virtual generic peripheral that act as virtual endpoints for the local processor's peripheral bus. Requests received by the virtual endpoints are encapsulated in interconnect packets and sent over an interconnect fabric to a device manager that accesses remote peripherals on a shared remote peripheral bus so that data can be returned. Ethernet Network Interface Cards (NIC), hard disks, consoles, and BIOS are remote peripherals that can be virtualized. Processors can boot entirely from the remote BIOS without additional drivers or a local BIOS. Peripheral costs are reduced by sharing remote peripherals.

US07925777B2 Content based data routing
A method of routing data from a source to one or more clients over a network, where the data conforms to a structured meta-language; in which the routing is performed by a server applying rules to the data itself, and not any address accompanying the data, to determine where to route that data to. The present invention is predicated on the counter-intuitive insight that data does not need to be concealed within a data envelope and given an address label in order to be routed effectively and efficiently. Instead, routing can be performed on the actual content of a message by applying simple routing rules to the data itself by intelligent ‘routing’ servers within the network which can unpack data from their message envelopes and intelligently filter/combine them with data unpacked from other messages to achieve a routing function.
US07925776B2 Wireless communication system for communication of audio data

US07925711B1 Centralized adaptive network memory engine
There is a constant battle to break even between continuing improvements in DRAM capacities and the growing memory demands of large-memory high-performance applications. Performance of such applications degrades quickly once the system hits the physical memory limit and starts swapping to the local disk. We present the design, implementation and evaluation of Anemone—an Adaptive Network Memory Engine—that virtualizes the collective unused memory of multiple machines across a gigabit Ethernet LAN, without requiring any modifications to the either the large memory applications or the Linux kernel. We have implemented a working prototype of Anemone and evaluated it using real-world unmodified applications such as ray-tracing and large in-memory sorting. Our results with the Anemone prototype show that unmodified single-process applications execute 2 to 3 times faster and multiple concurrent processes execute 6 to 7.7 times faster, when compared to disk based paging. The Anemone prototype reduces page-fault latencies by a factor of 19.6—from an average of 9.8 ms with disk based paging to 500 μs with Anemone. Most importantly, Anemone provides a virtualized low-latency access to potentially “unlimited” network memory resources.

In other words, the Type API reads/writes values for typed properties without regard to how the message is encoded with XML. Moreover, the two APIs are synced such that a value can be set using one API and retrieved using the other. For example, an XML API may be used as a writing mechanism for interacting with a value, while the Type API can read that same value, and vise-versa.
