    • An invention for reassigning data elements of an application to cache lines to decrease the occurrence of cache line faults is described. First, an application is executed and used in a typically manner. While the application is running, data is collected concerning the loading and storing of data elements. This collection process creates a massive volume of data that is then processed to determine correlations between the loading and storing pairs of elements within each of the application's data structures. These correlations provide a mechanism for weighing the probability of pairs of intra-structure data elements being accessed in sequence, which is best accomplished when the data elements are within a single cache line. A set of simultaneous equations describe the probabilities using the data recording the correlations. These equations are then solved using commonly known linear programming techniques to derive a suggested ordering of data structures. An interactive editor is then used to reorder these data elements in the derived preferred order as authorized by the programmer.
    • 描述了用于将应用的数据元素重新分配到高速缓存行以减少高速缓存线路故障的发生的发明。 首先,应用程序以典型的方式执行和使用。 当应用程序运行时,收集关于数据元素的加载和存储的数据。 此收集过程创建大量数据,然后处理数据,以确定每个应用程序的数据结构中的加载和存储对元素之间的相关性。 这些相关性提供了一种用于称量顺序地访问的结构内数据元素对的概率的机制,当数据元素在单个高速缓存行内时,这是最佳实现的。 一组联立方程使用记录相关性的数据描述概率。 然后使用公知的线性规划技术来解决这些方程,以得出建议的数据结构排序。 然后,交互式编辑器用于按照程序员的授权对派生优选顺序中的这些数据元素进行重新排序。

    • The invention describes a device for a self-service terminal which contains a card reading device, for preventing the possibility of data on a card which is to be read by the card reading device 10 being spied-out by means of a spying-out apparatus which is installed in the vicinity of the card reading device 10. The device comprises a protection apparatus 26 for generating a protective electromagnetic field which is suitable for impairing the functioning of the spying-out apparatus. The protection apparatus is controlled by a control unit 24 of the card reading device, which control unit also controls a card transportation apparatus 18 and/or a reading apparatus 20, 22 of the card reading device, such that the protective field is changed during reading of the card in the card reading device 10 such that it is ensured that reading of the card in the card reading device 10 is not impaired.
