An Architecture for Lossy Signal Compression

Konstantinides, Konstantinos; Natarajan, Balas K.



Abstract: Lossy compression schemes are often desirable in many signal processing applications such as the compression of ECG data. This paper presents a novel algorithm for lossy signal compression, based on the piece-wise linear approximation of functions. It also describes an architecture suitable for the single-chip implementation of the proposed algorithm. The design consists of control, two multiply/divide units, four adder/subtracter units, and an I/O interface unit. A simplified design for the compression of ECG data is also presented.
