摘要： A template for a logic synthesis command script is broken into smaller and functionally independent templates termed “micro-templates.” Using micro-templates, logic synthesis time may be significantly reduced. Each micro-template may correspond to a particular synthesis operation and may be enabled or disabled. Where synthesis of a particular set of synthesis operations is desired, the micro-templates corresponding to those synthesis operations are enabled.

摘要： A processor employs a store to load forward (STLF) predictor which may indicate, for dispatching loads, a dependency on a store. The dependency is indicated for a store which, during a previous execution, interfered with the execution of the load. Since a dependency is indicated on the store, the load is prevented from scheduling and/or executing prior to the store. The STLF predictor is trained with information for a particular load and store in response to executing the load and store and detecting the interference. Additionally, the STLF predictor may be untrained (e.g. information for a particular load and store may be deleted) if a load is indicated by the STLF predictor as dependent upon a particular store and the dependency does not actually occur. In one implementation, the STLF predictor records at least a portion of the PC of a store which interferes with the load in a first table indexed by the load PC. A second table maintains a corresponding portion of the store PCs of recently dispatched stores, along with tags identifying the recently dispatched stores. In another implementation, the STLF predictor records a difference between the tags assigned to a load and a store which interferes with the load in a first table indexed by the load PC. The PC of the dispatching load is used to select a difference from the table, and the difference is added to the tag assigned to the load.
摘要翻译：处理器使用存储来加载（STLF）预测器，其可以指示用于调度负载对存储的依赖性。对于在先前执行期间干扰负载的执行的存储器，指示依赖性。由于在存储器上指示依赖关系，所以在存储之前防止了负载的调度和/或执行。响应于执行负载并存储和检测干扰，STLF预测器被训练用于特定负载和存储的信息。此外，如果由STLF预测器指示负载依赖于特定存储并且实际上不发生依赖性，则STLF预测器可以是未经训练的（例如，针对特定负载的信息可以被删除）。在一个实现中，STLF预测器在由负载PC索引的第一表中记录干扰负载的商店的PC的至少一部分。第二个表维护最近派驻的商店的商店PC的相应部分，以及标识最近派发的商店的标签。在另一实现中，STLF预测器记录分配给负载的标签与由负载PC索引的第一表中的负载干扰的存储器之间的差异。调度负载的PC用于选择与表的差异，并将差值添加到分配给负载的标签。

摘要： Methods and systems for enabling users to register for notifications pertaining to electronic presentations of interest are described. The inventive methods and systems enable users to monitor many different electronic presentations without physically connecting to them for continuous play. Users can opt to monitor for the occurrence of an electronic presentation itself, or for events that might occur within various electronic presentations. The events can be monitored live through the use of meta information that is generated as the electronic broadcast is about to be, or is being broadcast. The meta information can be generated manually or automatically.

摘要： In a virtual machine environment, the invention enables creation of a long running, reusable, virtual machine are disclosed. The environment includes a shared heap where requisite runtime code to bring the virtual machine into a ‘ready’ mode are loaded, linked, verified, initialized and compiled. Subsequent virtual machines are started and jointly use the shared heap. Applications create their objects in ‘private heaps’ that are exclusively reserved for the respective applications. At the end of execution of an application, each private heap is reinitialized. Static initializers are run in a persistent area of each private heap. This persistent area is reset to its initial values in between execution of applications. This obviates the need to terminate the virtual machine.

摘要： A method of operation within a processor that permits load instructions following barrier instructions in an instruction sequence to be issued speculatively. The barrier instruction is executed and while the barrier operation is pending, a load request associated with the load instruction is speculatively issued. A speculation flag is set to indicate the load instruction was speculatively issued. The flag is reset when an acknowledgment of the barrier operation is received. Data that is returned before the acknowledgment is received is temporarily held, and the data is forwarded to the register and/or execution unit of the processor only after the acknowledgment is received. If a snoop invalidate is detected for the speculatively issued load request before the barrier operation completes, the data is discarded and the load request is re-issued.

摘要： Instead of a conventional task scheduler in which tasks having a high priority are preferentially scheduled, so that the execution of tasks with very low priorities is blocked, a “fair scheduler” is proposed in which each task (TA to TE) is assigned a counter (CNT) and a threshold value (THD), with the threshold value specifying a maximum number of execute cycles within which the task need not be executed immediately, and the counter counting those execute cycles within which the task is not executed. At the beginning of each execute cycle, a test is made to determine whether one of the counters exceeds the associated threshold value. If that is the case, one (TD) of the corresponding tasks (TC, TD) is selected by a selection criterion and executed, and its counter is reset. The counters assigned to the remaining tasks are incremented by one, and the execute cycle is repeated if it is found that at least one more of the tasks (TC) is waiting to be processed.

摘要： Detecting harmful or illegal intrusions into a computer network or into restricted portions of a computer network uses a features generator or builder to generate a feature reflecting changes in user and user group behavior over time. User and user group historical means and standard deviations are used to generate a feature that is not dependent on rigid or static rule sets. These statistical and historical values are calculated by accessing user activity data listing activities performed by users on the computer system. Historical information is then calculated based on the activities performed by users on the computer system. The feature is calculated using the historical information based on the user or group of users activities. The feature is then utilized by a model to obtain a value or score which indicates the likelihood of an intrusion into the computer network. The historical values are adjusted according to shifts in normal behavior of users of the computer system. This allows for calculation of the feature to reflect changing characteristics of the users on the computer system.

摘要： A processor includes a memory execution unit for executing load and store instructions and a replay system for replaying instructions which have not executed properly. The memory execution unit including an invalid store flag that is set for a store instruction if the replay system detects that the store instruction has not executed properly and is cleared if the store instruction has executed properly. If an invalid store flag is set for a store instruction, the replay system replays load instructions which are programmatically younger than the invalid store instruction until the store instruction executes properly.

摘要： The executing threads in CPU 100˜103 are checked at random intervals in a specified range by interrupt execution modules 109˜112, the results of the checks are stored in executing thread memory areas 113˜116 and values of counters 117˜120 that are corresponding to the executing threads are incremented. If the values of the counters 117˜120 exceed specified values, applicable threads are judged to be operating abnormally and priorities of the applicable threads are lowered so as to prevent the abnormal operations of the threads.
