Approximate computing can accept errors in computation systems to achieve better utilisation of hardware resources. has been successfully developed integrated circuits, such as approximate arithemtic circuits and accelerators. Unfortunately, recent works show that also have security vulnerabilities. Hardware Trojan is one the biggest threats security. However, very limited research conducted on...

In this paper we get some results and applications for duals and approximate duals of g-frames in Hilbert spaces. In particular, we consider the stability of duals and approximate duals under bounded operators and we study duals and approximate duals of g-frames in the direct sum of Hilbert spaces. We also obtain some results for perturbations of approximate duals.

Approximate multipliers are used in error-tolerant applications, sacrificing the accuracy of results to minimize power or delay. In this paper we investigate approximate using static segmentation. these circuits a set $m$ contiguous b...
