The authors describe the FSPU, which is a single-chip 22-bit signal and speech processor. The FSPU is based on a novel processing unit that achieves very high computation throughputs, while using floating-point arithmetic to achieve wide dynamic range and high precision. The developed architecture is intended to go beyond the limits of the standard general-purpose digital signal-processing implementations and to make floating-point signal processing more attractive. Testability, control flexibility, and area were strongly emphasized. A 3-μm CMOS prototype has been realized
