摘要： A method and apparatus are disclosed for treating a condition of a patient's heart includes placing a first electrode and a second electrode in a right ventricle of the heart. A reference electrode is placed within the patient and internal or external to the heart. A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The first component is transmitted to the first electrode. The second component is transmitted to the second electrode. The reference electrode is connected to the reference component which may be an electrical ground. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.

摘要： A pacemaker is disclosed which reestablishes or keeps the physiological electric conduction of the heart and a method of application. The pacemaker is a pulse generator, it has a ventricular output including at least two superimposed monopolar pulsewaves of reversed polarity between each other, with programmable configuration, with respect to a neutral which can be the pacemaker's metallic box or a third electrode in the case of a tripolar catheter. The catheter can have a deflectable sheath, with an electrode on its distal tip. The invention consists of a new pacemaker, and a method of application in the right ventricular septum, being able to use in order to facilitate the implantation and to avoid the connection and the disconnection, a sheath to check a proper place and then screw the catheter in said place. This method and the pacemaker are the responsible of reestablishing or preserving the physiological electrical conduction of the heart due to the creation of an alternative electric circuit and to the creation of a virtual electrode.

摘要： A combination of hardware and software collect profile data for asynchronous events, at code region granularity. An exemplary embodiment is directed to collecting metrics for prefetching events, which are asynchronous in nature. Instructions that belong to a code region are identified using one of several alternative techniques, causing a profile bit to be set for the instruction, as a marker. Each line of a data block that is prefetched is similarly marked. Events corresponding to the profile data being collected and resulting from instructions within the code region are then identified. Each time that one of the different types of events is identified, a corresponding counter is incremented. Following execution of the instructions within the code region, the profile data accumulated in the counters are collected, and the counters are reset for use with a new code region.

摘要： Instructions to be executed on a system are simulated. Representative simulation phases of the instructions, which most affect simulation results of the instructions to be executed on the system, are dynamically determined. For each representative simulation phase of the instructions, a model is selected from a number of models that provides specified accuracy with a minimal amount of simulation time, and the representative simulation phase is simulated using the model selected. The simulation results for the instructions to be executed on the system are then output.

摘要： Techniques are described for providing an enhanced cache coherency protocol for a multi-core processor that includes a Speculative Request For Ownership Without Data (SRFOWD) for a portion of cache memory. With a SRFOWD, only an acknowledgement message may be provided as an answer to a requesting core. The contents of the affected cache line are not required to be a part of the answer. The enhanced cache coherency protocol may assure that a valid copy of the current cache line exists in case of misspeculation by the requesting core. Thus, an owner of the current copy of the cache line may maintain a copy of the old contents of the cache line. The old contents of the cache line may be discarded if speculation by the requesting core turns out to be correct. Otherwise, in case of misspeculation by the requesting core, the old contents of the cache line may be set back to a valid state.

摘要翻译： 描述了用于为多核处理器提供增强的高速缓存一致性协议的技术，所述多核处理器包括用于高速缓冲存储器的一部分的无数据的投机请求（SRFOWD）。 使用SRFOWD，可以仅提供确认消息作为请求内核的答案。 受影响的缓存行的内容不需要作为答案的一部分。 增强的高速缓存一致性协议可以确保在请求核心的错误配置的情况下存在当前高速缓存行的有效副本。 因此，高速缓存行的当前副本的所有者可以维护高速缓存行的旧内容的副本。 如果请求的核心的推测证明是正确的，则可以丢弃该高速缓存行的旧内容。 否则，在请求核心发生错误的情况下，可以将高速缓存行的旧内容设置回有效状态。
