### Abstract

The author proposes dedicated high-speed architectures for nibble-serial implementation of arithmetic operations (such as addition, multiplication, division, and square root) using a two's-complement fixed-point number system (all numbers assumed to lie between -1 and +1). Nibble-serial circuits are obtained by systematically applying the unfolding transformation on the corresponding bit-serial circuits. Nibble-serial arithmetic circuits input W_{1}-b of a word or sample in a single cycle, and the complete word is input in W_{2} cycles, where W = W_{1}W_{2} is the word length. W_{1} need not be 4 in a nibble-serial implementation, but can be any divisor of the word length.
