“…To learn the concept of integrated or embedded systems and their importance for ASR it is necessary to explain what Very Large Scale Integration (VLSI) technology is. VLSI is the process of creating integrated circuits by combining thousands of transistorbased circuits into a single chip (S. Kung, 1985;Barazesh et al, 1988;Cheng et al, 1991). VLSI began in the 70's when complex semiconductors were being developed.…”

“…These algorithms assume operations in real number systems. However, complex number computations also have imporantant roles in various signal processing and scientific applications such as complex orthogonal transformations, convolutions, correlations, and filtering [4]. Recent papers have demonstrated the emergence of on-line algorithms for complex number arithmetic.…”

A class of on-line algorithms for complex number arithmetic is presented. These algorithms adopt a redundant complex number system (RCNS) to represent complex numbers as a single number. Such a scheme simplifies the specification of the design, and has the additionaleffect that singleprecision complex arithmetic can be easily reconfigured for double-precision real arithmetic. We present cost delay comparisons with the more conventional approach to show a significant improvement, demonstrating that the presented algorithms are attractive for VLSI systems demanding complex number operations.
