  • Patent number: 8149904
    Abstract: Provided is a system and method for a modem including one or more processing paths. Also included is a number of interconnected modules sequentially arrayed along the one or more paths. Each module is configured to (i) process signals passed along the paths in accordance with the sequence and (ii) implement predetermined functions to perform the processing. Further, each of the modules has a particular degree of functional programmability and the degrees of functional programmability monotonically vary in accordance with the sequence.
    Type: Grant

  • Patent number: 7809902
    Abstract: Provided is a system and method for de-interleaving a data stream stored in a buffer having a plurality of memory locations. Each location has a memory width of (W) bytes and the data stream is formed of a number of data words each including (N) number of data bytes, and (N) is a non-integer multiple of the width (W). The method includes storing the data words into respective memory locations and appending each of the stored data words with number (X) of dummy bytes, a sum of (N)+(X) being an integer multiple of the width (W). The appended dummy bytes are then stored in the respective memory locations.
