Abstract: An apparatus for enabling improved map feature detection may include a processor. The processor may be configured to receive data including first signal strength information defining respective strengths of position message signals received over corresponding portions of a first position history, analyze the first signal strength information with respect to change in the respective strengths of the position message signals, and enable updating of map data with respect to a feature associated with a travel route corresponding to the first position history based on analyzing the first signal strength information. A method and computer program product for enabling improved map feature detection are also provided.

Abstract: A system for providing management of shared memory for concurrent access is provided. The system includes a hardware element, a software element, and a memory that is accessible by the hardware and software elements. The memory includes control data that provides logical information describing the structure of the memory and the location of data within the memory. The software element may be executed to cause the control data to be written/updated to reflect alterations to the memory. By accessing the control data of the memory, the hardware element is able to identify a location in the memory to which to write data. In this way, the hardware element may write data to the memory without interacting with the software element while writing data. An indicator may also be provided to direct the hardware element to a location of the memory to which to write data.

Abstract: A method includes constructing a data unit including a plurality of parts stored in a plurality of regions of a memory, and instructing a controller to serialize the data unit and to transfer the data unit to a destination.
