    • The present invention includes a system and method for selecting a unique geographic feature, including a mobile device that uses position and orientation sensors to determine a user position and a user orientation. The mobile device is adapted for wireless communication with a database that houses or has access to data concerning geographic features, as well as processing and computing means for calculating specific geographic relations discussed in further detail below. The system of the present invention further includes means for selecting among those features that are topologically related to the polygon. These include means for defining the geometry of the polygon, means for filtering those features that should not be within the geometry of the polygon, and means for ranking those features within the polygon. The method of the present invention is operable in conjunction with the system through the system hardware and software.
    • 本发明包括用于选择唯一地理特征的系统和方法,包括使用位置和方向传感器来确定用户位置和用户取向的移动设备。 移动设备适于与容纳或具有关于地理特征的数据的数据库的无线通信,以及用于计算下面进一步详细讨论的特定地理关系的处理和计算装置。 本发明的系统还包括用于在与多边形拓扑相关的那些特征中进行选择的装置。 这些包括用于定义多边形的几何形状的装置,用于过滤不应该在多边形几何中的那些特征的装置,以及用于对多边形内的这些特征进行排名的装置。 本发明的方法可以通过系统硬件和软件与系统一起工作。

    • A multi-threaded embedded processor that includes an on-chip deterministic (e.g., scratch or locked cache) memory that persistently stores all instructions associated with one or more pre-selected high-use threads. The processor executes general (non-selected) threads by reading instructions from an inexpensive external memory, e.g., by way of an on-chip standard cache memory, or using other potentially slow, non-deterministic operation such as direct execution from that external memory that can cause the processor to stall while waiting for instructions to arrive. When a cache miss or other blocking event occurs during execution of a general thread, the processor switches to the pre-selected thread, whose execution with zero or minimal delay is guaranteed by the deterministic memory, thereby utilizing otherwise wasted processor cycles until the blocking event is complete.
    • 一种多线程嵌入式处理器,其包括持续存储与一个或多个预选高使用线程相关联的所有指令的片上确定性(例如,划伤或锁定的高速缓存)存储器。 处理器通过从便宜的外部存储器读取指令(例如,通过片上标准高速缓冲存储器)或使用其他潜在的慢速非确定性操作(例如来自该外部存储器的直接执行)来执行通用(未选择)线程 这可能导致处理器在等待指令到达时停止。 当在一般线程的执行期间出现高速缓存未命中或其他阻塞事件时,处理器切换到预先选择的线程,该线程的执行以零或最小延迟由确定性存储器保证,从而利用其他浪费的处理器周期,直到阻塞事件 做完了。
