Side-fed superlattice for the production of linear predictor and filter coefficients.

摘要

Signal processing structures for providing direct prediction coefficients and direct LS-FIR filter coefficients are disclosed. The structures include one or more processors, and a storage and retrieval structure for selectively storing predictor and filter coefficients and intermediate variables, to thereby allow the one or more real processors to emulate a plurality of virtual processors, which take the form of a side-fed superlattice structure, in the case of linear prediction, and a side-fed superlattice-superladder structure, in the case of direct LS-FIR filtering.
