Abstract
A filter processor implements the least mean squares (LMS) algorithm in an N tap digital filter in (N+1) time cycles, where N is an integer. A filter structure is shown which is implemented with a processor having an update portion and a convolution portion. A single memory is shared between the two portions, and the same data is concurrently coupled to both portions for concurrent use. The filter may be efficiently pipelined wherein successive adaptive and convolution operations are executed to efficiently implement an N tap filter with a minimum amount of circuity.
