Stochastic computing, which is an approximate computation with probabilities (called stochastic numbers), draws attention as an alternative method of deterministic computing. In this paper, we discuss a design of compact and accurate stochastic circuits. Stochastic circuits are known as a way to stochastically compute complex calculation at low hardware(More)
This paper proposes a self-test method of coarse grain dynamically reconfigurable processors (DRPs) without hardware overhead. In the method, processor elements (PEs) compose a test frame, which consists of test pattern generators (TPGs), processor elements under test (PEUTs) and response analyzers (RAs), while testing themselves one another by changing(More)
Threshold testing, which is a VLSI testing method based on the acceptability of faults, is effective in yield enhancement of VLSIs and in selectively hardening VLSI systems. A test generation algorithm for generating test patterns for unacceptable faults has been proposed, which is based on the 16-valued logic system. In this paper, we propose a fast test(More)
