Abstract From the Canadian patent

An optimal parametric signal processor which, receives autocorrelation coefficients provides, lattice coefficients in an optimal manner and allows, the use of any number of available parallel processing units. The signal processor may be implemented in a fully parallel or fully sequential manner or in a, "parallel-partitioned" implementation which provides the benefits of parallel processing, manageable hardware complexity, and optimal signal processing for a given number of available processors. By using a "lattice basic cell" structure, hardware complexity is minimized.
