Abstract: A plurality of systems for routing signals are described. The system includes a cross point switch that can couple any one of a plurality of input terminals to a plurality of output processor terminals. Signals received at the input terminals are coupled to corresponding output terminals and are processed by output modules. The resulting processed signals are provided at output terminals. In some embodiments, one or more input modules are provided to process input signal prior to routing through the cross-point switch.

Abstract: Aspects of the invention relate to improvements to the Least Recently Used (LRU) cache replacement method. Weighted LRU (WLRU) and Compact Weighted LRU (CWLRU) are CPU cache replacement methods that have superior hit rates to LRU replacement for programs with poor locality, such as network protocols and applications. WLRU assigns weights to cache lines and makes replacement decision by comparing weights. When a cache line is first brought into the cache, it is assigned an initial weight. Weights of cache lines in WLRU increase when hit and decrease when not hit. Weights in WLRU also have upper limits, and the weight of a cache line never increases beyond the upper limit. CWLRU is a more space-efficient implementation of WLRU. Compared to WLRU, CWLRU uses fewer bits per cache line to store the weight.

Abstract translation: 本发明的方面涉及对最近最少使用（LRU）高速缓存替换方法的改进。 加权LRU（WLRU）和紧凑加权LRU（CWLRU）是CPU缓存替换方法，对于局部性差的程序（如网络协议和应用程序），具有优于LRU替换的命中率。 WLRU将权重分配给高速缓存行，并通过比较权重进行替换决策。 当缓存行首先被带入高速缓存时，它被分配一个初始权重。 WLRU中的高速缓存线的重量在击中时增加，而不受命中则减小。 WLRU中的权重也有上限，缓存行的权重不会超过上限。 CWLRU是WLRU更节省空间的实施。 与WLRU相比，CWLRU使用每个缓存行更少的位来存储权重。

Abstract: A security token access device, a user device such as a computing device or communications device, and a method for managing multiple connections between multiple user devices and the access device. The access device maintains connection information, including security information, for each user device securely paired with the access device. Each time a new user device is paired with the access device, the access device transmits a notification to the user devices already paired to the user device. A user may provide instructions to the access device to terminate a pairing with one of the user devices by overwriting at least a portion of the connection information associated with the designated user device. A user device may further request a listing of all user devices currently paired with the access device.

Abstract: A system and method are described herein for standardizing an IT policy that is used to configure devices operating on a network. An IT policy can be generated that applies to a group of users or to one or more special users without having to define and store a new IT policy for each special user. This can be achieved by specifying global and per-user IT policy rules and merging these rules as needed to produce IT policy data.

Abstract: The present invention provides a secure JTAG interface to an application-specific integrated circuit (ASIC). In the preferred embodiment the invention operates through the combined efforts of a Security Module (SM) comprising a state machine that controls the security modes for the ASIC, and a Test Control Module (TCM) which contains the JTAG interface. The TCM operates in either a restricted mode or an unrestricted mode, depending on the state of the SM state machine. In a restricted mode, only limited access to memory content is permitted. In an unrestricted mode, full access to memory content is permitted.

Abstract translation: 本发明提供了一种用于专用集成电路（ASIC）的安全JTAG接口。 在优选实施例中，本发明通过包括控制ASIC的安全模式的状态机和包含JTAG接口的测试控制模块（TCM）的安全模块（SM）的组合进行操作。 根据SM状态机的状态，TCM以受限制模式或非限制模式运行。 在限制模式下，只允许对存储器内容的访问有限。 在无限制模式下，允许完全访问内存内容。

Abstract: A system and method for processing messages being composed by a user of a computing device (e.g. a mobile device). Embodiments are described in which the performance of certain tasks is initiated before a direction is received from a user to send a message being composed by the user. This may involve, for example, “pre-fetching” security-related data that will be required in order to send a message that is in the process of being composed by the user securely. Such data may include security policy data, certificate data, and/or certificate status data, for example.

Abstract: A system and method for determining a security encoding to be applied to a message being sent by a user of a computing device. In one broad aspect, the device comprises a processor configured to: determine whether a general message encoding configuration setting indicates that when a security encoding is to be applied to a message then the security encoding is to be established by a policy engine; if the general message encoding configuration setting so indicates, query the policy engine for the security encoding to be applied to the message; otherwise, determine the security encoding to be applied to the message in accordance with a user-selected security encoding; and apply the determined security encoding to the message prior to transmission of the message to at least one recipient.

Abstract: Several push-pull linear hybrid class H amplifiers are disclosed. A split power rail provides a positive supply rail and a negative supply rail in response to a power supply control voltage. A push-pull amplifier stage is powered by the positive and negative supply rails. The amplifier stage receives an input signal and provides a corresponding amplified output signal. A power supply control circuit provides the power supply control voltage in response to the smaller of the positive and negative supply rails, and the input signal.
