摘要： Maintaining a cache of indications of exclusively-owned coherence state for memory space units (e.g., cache line) allows reduction, if not elimination, of delay from missing store operations. In addition, the indications are maintained without corresponding data of the memory space unit, thus allowing representation of a large memory space with a relatively small missing store operation accelerator. With the missing store operation accelerator, a store operation, which misses in low-latency memory (e.g., L1 or L2 cache), proceeds as if the targeted memory space unit resides in the low-latency memory, if indicated in the missing store operation accelerator. When a store operation misses in low-latency memory and hits in the accelerator, a positive acknowledgement is transmitted to the writing processing unit allowing the store operation to proceed. An entry is allocated for the store operation, the store data is written into the allocated entry, and the target of the store operation is requested from memory. When a copy of the data at the requested memory space unit returns, the rest of the allocated entry is updated.

摘要： An advance over the prior art is achieved through an efficient method for an admission control algorithm and a scheduling mechanism that complement each other in providing the following three classes of service. A first class of service is termed Class 1 where users specify a nominal amount of bandwidth desired. A second, lower tier service class is termed Class 2, wherein users specify a nominal and minimum amount of bandwidth desired when entering into a network connection. A third server class is Class 3, where Class 3 users are treated as best effort users. For Class 1 users the methodology of the present invention provides a guaranteed nominal amount of bandwidth. The admission control procedure ensures that Class 1 users are admitted only if resources exist to satisfy the nominal bandwidth requirements of the Class 1 users. Class 2 users are admitted if resources exist to satisfy the minimum bandwidth requirements of the user. Class 2 users are served with a bandwidth of up to their nominal bandwidths if there is capacity left after serving the Class 1 users with their nominal capacities. Class 3 users are served only if the Class 2 users have received their nominal bandwidths.
摘要翻译：通过用于准入控制算法和调度机制的有效方法来实现现有技术的进步，所述准入控制算法和调度机制在提供以下三类服务时相互补充。第一类服务被称为1类，用户指定所需的额定带宽量。第二个较低级别的服务类称为2类，其中用户在进入网络连接时指定所需的标称和最小带宽量。第三个服务器类是Class 3，其中Class 3用户被视为尽力而为的用户。对于1类用户，本发明的方法提供了有保证的标称带宽量。接纳控制程序确保只有在存在资源以满足1类用户的标称带宽要求的情况下才允许1类用户。如果存在资源以满足用户的最低带宽要求，则允许2类用户使用。如果在服务具有标称容量的Class 1用户之后剩余容量，则Class 2用户的带宽可达到其标称带宽。仅当Class 2用户已经收到其标称带宽时才能使用3级用户。

摘要： Systems and methodologies are described that facilitate communication in a wireless network environment. In particular, access points can dynamically adjust transmit power and/or carrier-sensing thresholds to allow multiple access points to communicate concurrently. In aspects, access points exchange node information, including RSSI and node addresses, of nearby nodes. The node information can be utilized to detect hidden nodes and estimate interference levels. Transmit power and/or carrier-sensing thresholds can be modified as a function of distance between source and destination access points, interference from hidden nodes, transmission rates, and/or path loss.

摘要： Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier-to-interference (C/I) ratio, at an access point (AP) are provided. In this manner, such a user terminal may help avoid or compensate for imbalances in received radio frequency (RF) power between UL signals received from multiple user terminals by the AP. For example, the transmit power at each user terminal may be controlled in an effort to achieve a target post-processing C/I ratio of 28 dB per spatial stream in an effort to reduce large power imbalances and optimize throughput per user terminal. The user terminal and the AP may compose part of a multiple-input multiple-output (MIMO) communication system utilizing spatial-division multiple access (SDMA) techniques.

摘要： Techniques and apparatus for embedding one or more bits of 802.11 Very High Throughput (VHT) information in existing IEEE 802.11 preamble fields are provided. As will be described herein, because different combinations of modulation techniques, coding schemes, and transmission lengths result in the same transmit time (e.g., in terms of symbol length), a clever choice of modulation, coding, and length may allow some extra information to be embedded in a legacy field for use by VHT stations. In this manner, the total VHT preamble transmission time may potentially be reduced, thereby increasing the efficiency of the physical layer (PHY). Moreover, the embedded bits may most likely be invisible to legacy stations, since the transmission time that such stations compute will be independent of these bits by design.
摘要翻译：提供了用于在现有的IEEE 802.11前导字段中嵌入一个或多个802.11非常高吞吐量（VHT）信息的技术和装置。如本文将要描述的，因为调制技术，编码方案和传输长度的不同组合导致相同的发送时间（例如，在符号长度方面），调制，编码和长度的巧妙选择可以允许一些额外的信息嵌入到传统领域以供VHT站使用。以这种方式，可以潜在地减少总VHT前导码传输时间，从而提高物理层（PHY）的效率。此外，嵌入式位可能很可能对于传统站是不可见的，因为这样的站计算的传输时间将通过设计独立于这些位。

摘要： An adaptable decision parameter is used to determine whether to react to resource utilization messages. The decision parameter may comprise a decision threshold that is adapted based on received resource utilization messages. The decision parameter may comprise a probability that is used to determine whether to react to a received resource utilization message. Such a probability may be based on, for example, one or more channel conditions, the number of interferers seen by a node, the number of received resource utilization messages, or some other form of resource utilization message-related information.

摘要： Providing fairness-based metrics for managing inter-sector interference of a mobile AN is described herein. By way of example, accumulation of resource utilization messages (RUMs) at a sector of the mobile AN can be based at least in part on a performance metric of that sector as compared with one or more neighboring sectors. In at least one aspect, performance metrics of multiple sectors of the mobile AN can be aggregated and a RUM accumulation rate of each sector is determined based on the aggregated metric. Accumulation rates can further be updated periodically as sector and/or aggregated metrics of the mobile AN change. Accordingly, accumulation and utilization of RUMs is based on inter-sector fairness to optimize overall wireless communication quality of service for the mobile AN.

Two types of events are tracked in one of two different ways: first by counting/tracking prefetch operations, either globally or on a per instruction address basis and then by counting/tracking cache pollutions, either globally or on a per instruction address basis.

摘要： An automated design system for VLIW processors explores a parameterized design space to assist in identifying candidate processor designs that satisfy desired design constraints, such as processor cost and performance. A VLIW synthesis process takes as input a specification of processor parameters and synthesizes a datapath specification, an instruction format design, and a control path specification. The synthesis process also extracts a machine description suitable to re-target a compiler. The re-targeted compiler generates operation issue statistics for an application program or set of programs. Using these statistics, a procedure for searching the design space can extract internal resources utilization information that is used to determine new candidate processors for evaluation.
