Abstract: A multi-port, multi-mode Reed Solomon (RS) forward error correction system includes a plurality of data in lines, each associated with a data port. The system includes a syndrome block (SDM) that has a plurality of syndrome slices and a SDM switching logic. An input of a SDM slice couples with a data in line from the plurality of data in lines. The switching logic couples with an interface port width (IFW) line a mode line. The IFW line identifies a number of data in lines tied together and the mode line to identify a RS mode. A reformulated inversionless Berlekamp-Massey (RiBM) block has a plurality of RiBM slices and a RiBM switching logic. A Chien Forney (ChFr) block has a plurality of ChFr slices. An error evaluation magnitude (ErEval) block has a plurality of ErEval slices. A plurality of adders couple with an output of a corresponding ErEval slice.

Abstract: Systems and methods for distributed downhole sensing of operating parameters in an ESP utilizing MEMS sensors. In one embodiment, an ESP is installed in a well. The ESP has a pump, a gas separator, a seal section and a motor. Multiple MEMS sensors are positioned within one or more of the ESP components. Each of the MEMS sensors has a sensor component and on-board circuitry that are formed on a substrate. Each MEMS sensor's sensor component senses a corresponding operating parameter and provides sensed information to the on-board circuitry, which processes the received sensor signal as needed and provides the processed information at an output of the MEMS sensor. The outputs of the different MEMS sensors can be networked together, and the sensor information for the different operating parameters can be communicated to equipment at the surface of the well via a common electrical line.
