摘要： A solution for cooperative data prefetching that enables software control of a memory-side data prefetch and/or a processor-side data prefetch is provided. In one embodiment, the invention provides a solution for generating an application, in which access to application data for the application is improved (e.g., optimized) in program code for the application. In particular, a push request, for performing a memory-side data prefetch of the application data, and a prefetch request, for performing a processor-side data prefetch, are added to the program code. The memory-side data prefetch results in the application data being copied from a first data store to a second data store that is faster than the first data store while the processor-side data prefetch results in the application data being copied from the second data store to a third data store that is faster than the second data store.

摘要翻译：提供了一种用于协同数据预取的解决方案，其实现对存储器侧数据预取和/或处理器侧数据预取的软件控制。在一个实施例中，本发明提供了一种用于生成应用的解决方案，其中在应用的程序代码中改进（例如，优化）应用程序的应用数据的访问。特别地，用于执行应用数据的存储器侧数据预取的推送请求和用于执行处理器侧数据预取的预取请求被添加到程序代码。存储器侧数据预取导致应用数据从第一数据存储器复制到比第一数据存储器更快的第二数据存储器，而处理器侧数据预取导致应用数据从第二数据存储器复制到比第二数据存储更快的第三数据存储。

摘要： A method for selecting a line to replace in an inclusive set-associative cache memory system which is based on a least recently used replacement policy but is enhanced to detect and give special treatment to the reloading of a line that has been recently cast out. A line which has been reloaded after having been recently cast out is assigned a special encoding which temporarily gives priority to the line in the cache so that it will not be selected for replacement in the usual least recently used replacement process. This method of line selection for replacement improves system performance by providing better hit rates in the cache hierarchy levels above, by ensuring that heavily used lines in the levels above are not aged out of the levels below due to lack of use.
摘要翻译：一种用于在包含集合关联高速缓存存储器系统中选择要替代的方法，该系统基于最近最近使用的替换策略，但是被增强以检测并对最近被抛出的行的重新加载进行特殊处理。在最近被淘汰之后重新加载的行被分配一个专门的编码，它暂时优先地将高速缓存中的行优先，以便在通常的最近最近使用的替换过程中不被选择进行替换。这种替代选线方法通过在上述缓存层次结构中提供更好的命中率来提高系统性能，通过确保上述级别中的使用过多的线路由于缺乏使用而不会超出以下级别。

摘要： A communication system for multiple users whereby an automatic indication of away status is prompted immediately upon a user's departure from the vicinity of a computer or other medium. In a preferred embodiment, this is accomplished, in an instant messaging environment, via a video camera arrangement whereby, upon there being a detection of a user's absence from the immediate vicinity, an automatic prompt is made to indicate away status for the user.

摘要： A method of detecting double-symbol errors and correcting single-symbol errors in a data stream being transmitted in a computer system, e.g., from a memory array to a memory controller. The method includes decoding the data stream which was encoded using a logic circuit which had, as inputs, the data being sent and two address parity bits derived from the system address of the data. Data retrieved from the wrong address can be detected by this code. The logic circuit is described by a parity-check matrix for this (146,130) code comprising 128 data bits, 16 check bits, and 2 address parity bits. Although the symbol width of the code is four bits, the code can also be used effectively in memory systems where the memory chip width is eight bits.
