    • A predictive device system includes a first device motion control input, determines a desired first device motion using the first device motion control input, and provides actual first device motion using the first device motion control input. The predictive system also determines motion inherent in a received signal using the actual first device motion, determines a difference to be simulated in a second device signal using the desired first device motion and the motion inherent in the received signal, and outputs a predictive signal using the first device motion control input and the difference to be simulated in the second device signal.
    • 预测装置系统包括第一装置运动控制输入,使用第一装置运动控制输入确定期望的第一装置运动,并使用第一装置运动控制输入提供实际的第一装置运动。 预测系统还使用实际的第一设备运动来确定接收信号中固有的运动,使用期望的第一设备运动和接收信号中固有的运动来确定要在第二设备信号中仿真的差异,并且使用 第一装置运动控制输入和在第二装置信号中要模拟的差值。

    • A selective multilevel caching method and system including a main memory and a plurality of cache memories are disclosed. The main memory and cache memories are arranged in a multilevel hierarchy: the main memory is at the lowest hierarchical level; the cache memory that is coupled directly to the central processing unit (CPU) is at the highest hierarchical level; and the remaining cache memories are coupled in the hierarchy at intermediate hierarchical levels therebetween. Each hierarchical level contains cache logic as well as a cache memory. Each cache logic responds to a cache level code that is associated with an address specified in each CPU read or write data request. The cache level code specifies the highest hierarchical level at which data associated with the data request may be written. Each cache logic uses the cache level code to determine if data will be written to the cache memory at the same hierarchical level as that cache logic. Each CPU write request further includes a cache control code. The cache control code indicates whether each cache level is designated as a write-allocate cache level. Each cache logic responds also to the cache control code to further determine if data will be written to the cache memory at the same hierarchical level as that cache logic.
    • 公开了一种包括主存储器和多个高速缓冲存储器的选择性多级缓存方法和系统。 主存储器和高速缓冲存储器被布置在多层次层次中:主存储器处于最低层级; 直接连接到中央处理单元(CPU)的高速缓存存储器处于最高层级; 并且其余的高速缓存存储器在它们之间的中间层级中被分层结合。 每个层级都包含高速缓存逻辑以及高速缓存。 每个高速缓存逻辑响应与每个CPU读或写数据请求中指定的地址相关联的高速缓存级代码。 缓存级别代码指定可以写入与数据请求相关联的数据的最高层级。 每个高速缓存逻辑使用高速缓存级代码来确定数据是否将以与该高速缓存逻辑相同的层级写入缓存存储器。 每个CPU写请求还包括缓存控制代码。 高速缓存控制代码指示每个高速缓存级别是否被指定为写分配高速缓存级别。 每个高速缓存逻辑还响应高速缓存控制代码,以进一步确定数据是否将以与该高速缓存逻辑相同的层级写入高速缓冲存储器。
