Abstract: A bidirectional radio frequency identification (RFID) network system and method are presented. The system allows users to configure, monitor, and manage different sensor devices by using a graphical user interface real-time. The reconfiguration is done through a network management computer at the top system level that receives user input, generates code images according to the user input, and appropriately routes the code images to sensor routers that directly control the sensors. If the system is multi-layered, some code images are also sent to the intermediate-level network management computers. The system allows users to not only monitor a business flow but react to problematic situations quickly by adjusting the workflow. The aspect-oriented nature of the system allows users to reconfigure the system based only the Functionality aspects without worrying about the Partitioning aspects (e.g., how the network and the sensors are physically connected).

Abstract: The apparatus includes a first SOVA decoder that generates a first path reliability value from a channel value, a parity symbol and a first a priori likelihood value. A first decorrelation unit generates a first extrinsic symbol reliability value by decorrelating the channel value and the first a priori likelihood value from the path reliability value. A first symbol reliability saturation unit saturates the first extrinsic symbol reliability value to generate a first saturated extrinsic symbol reliability value. A first interleaver interleaves the first saturated extrinsic symbol reliability value to generate a second a priori likelihood value. A second interleaver interleaves the channel value to generate an interleaved channel value. A second SOVA decoder generates a second path reliability value from an interleaved parity symbol, the second a priori likelihood value, and the interleaved channel value.

Abstract: The present invention is directed to a digital signal processor having a local buffer for storing decoded instruction words during the first pass through a program loop, so that subsequent iterations through the program loop can be accomplished without the use of the instruction fetch and decode circuitry, thereby saving power.
