| Abstract(in English) | Stochastic Computing (SC) is an approximation calculation method using stochastic numbers (SNs) which represent the ratio of 1's in bit strings. When we calculate $f(x)$ by SC, we need to generate many SNs whose values are equal to constant values.Therefore, if we need to generate many constant SNs, the hardware overhead becomes huge.In this paper, we propose an efficient scheme to generate constant SNs with reasonably low hardware overhead without increasing errors.Our experimental results suggest that our proposed scheme is in general very useful to provide reduce the hardware overhead for generating constant SNs without increasing errors. |
