Conference Proceeding: Increase in reliability of on-line testing methods using natural time redundancy
[show abstract] [hide abstract]
ABSTRACT: This paper addresses to questions of on-line testing for the computing circuits processing the approximate data. A problem of low reliability of on-line testing methods in checking the result is considered. This problem is connected to ignoring the natural time redundancy, which allows detecting the errors produced by the circuit fault during some interval of time. It reduces detection probability of errors, which are essential to reliability of result. The increase of this probability leads to detection of inessential errors and reduces reliability of on-line testing methods. The method of segments checking, which provides check of segments in the calculated result with the error detection probabilities determined by the natural time redundancy, is offered. This method significantly increases reliability in checking the result.Design & Test Symposium (EWDTS), 2010 East-West; 10/2010 -
Conference Proceeding: Parity prediction method for on-line testing of a Barrel-shifter
[show abstract] [hide abstract]
ABSTRACT: This paper addresses the problem of on-line testing of floating-point computing circuits. The problem is connected with the use of the truncated operations in the part of mantissas processing. The arithmetic shift performed on a Barrel-shifter is the most often used truncated operation. Known approaches to on-line testing of the Barrel-shifter are based on duplication of the truncated operation or on its restoring to a long shift. This makes of the error detection scheme more complex. Known residue checking method, which implements a prior computation of the check results for all causes of a shift reduces the check hardware overhead from square dependence on an operand size to a linear one. However this method requires to perform a series of complex operations for generating and processing of the check codes by modulo. We propose the parity prediction method that significantly simplifies the error detection scheme of a Barrel-shifter by using simple check operations.Design & Test Symposium (EWDTS), 2008 East-West; 11/2008
