摘要: An embodiment comprises and apparatus having an image capture device with an image axis and a gyroscope operable to indicate the orientation of the image axis. An embodiment of a capsule endoscopy system comprises an imaging capsule and an external unit. The imaging capsule may comprise an image capture device having an image axis and a gyroscope operable to indicate the orientation of the image axis. The external unit may comprise a gyroscope operable to indicate an orientation of a subject and a harness wearable by a subject and operable to align the gyroscope with the subject. The imaging capsule may send and image to an external unit for processing and display, and the external unit may provide for calculation of the image-axis orientation relative to the body.

摘要: In a network-on-chip (NoC) system, multiple data messages may be transferred among modules of the system. Power consumption due to the transfer of the messages may affect a cost and overall performance of the system. A described technique provides a way to reduce a volume of data transferred in the NoC system by exploiting redundancy of data messages. Thus, if a data message to be sent from a source in the NoC includes so-called “zero” bytes that are bytes including only bits set to “0,” such zero bytes may not be transmitted in the NoC. Information on whether each byte of the data message is a zero byte may be recorded in a storage such as a data structure. This information, together with non-zero bytes of the data message, may form a compressed version of the data message. The information may then be used to uncompress the compressed data message at a destination.

摘要: In mesh networks having multiple nodes that communicate data to and from each other, a great number of data transmissions may be initiated and carried out to get data to a proper processing node for execution. To get data where it needs to go (e.g., the proper destination node), a routing algorithm is used to define a set of rules for efficiently passing data from node to node until the destination node is reached. For the purpose of assuring that all data is properly transferred from node to node in a reasonably efficient manner, a routing algorithm may define subsets of nodes into regions and then send data via the regions. Even greater overall efficiency may be realized by recognizing specific adjacency relationships among a group of destination nodes and taking advantage of such adjacencies by rerouting data through regions other than the region in which a destination node resides.
