Multiplication is performed frequently when implementing finite impulse response (FIR) filters. In most cases, rounded products are necessary to circumvent the growth of word length in order to reduce the area requirement and power dissipation and to speed up the circuit. However, due to rounding or truncating, errors are caused. In addition, in the FIR filter implementation, because of internal truncation,...
Superconductive rapid single flux quantum (RSFQ) digital computing system has the tendency to achieve the operating rate of several hundred GHz. Compare to the semiconductor partner, with the pulse width about picoseconds and clock rate of several hundred GHz, the timing uncertainty from fabrication process variations makes it impossible to achieve the large scale integrated chip with global synchronization...
In this paper, we present an algorithm for computing the bounds on energy-efficiency of digital very large scale integration (VLSI) systems in the presence of deep submicron noise. The proposed algorithm is based on a soft-decision channel model of noisy VLSI systems and employs information-theoretic arguments. Bounds on energy-efficiency are computed for multimodule systems, static gates, dynamic...
