Self-exercising self testing k-order comparators

چکیده
In this paper we give a systematic method to design Self Exercising (SE) [ 11 self testing k-order comparators. The k-order comparator is defined as a combinational circuit that compares two operands and decides if these differ in less than k bits. According to this definition the usual equality comparator is the 1st-order comparator. Also in this paper we discuss the applicability of the k-order comparators in the implementation of (k1)-EC/AUED, (k-1)-EC/d-ED/AUED, (k1)-EC/d-UED and (k-1)-EC/dED/f-UED codes [2-7] as well as in the design of a fault tolerant cache memory [9] and broadcast networks.

able to map each input noncode word to an output noncode word, and thus, the SCD property of the whole checker is not lost. Examples illustrating the points a, b, and c have been given in another report [171. V. CONCLUSIONS The paper discusses some important aspects of self-checking checkers and highlights some problems concerning the necessity of the fault secure property for SCD checkers. Som...
متن کاملLow Power March Memory Test Algorithm for Static Random Access Memories (TECHNICAL NOTE)
Memories are most important building blocks in many digital systems. As the Integrated Circuits requirements are growing, the test circuitry must grow as well. There is a need for more efficient test techniques with low power and high speed. Many Memory Built in Self-Test techniques have been proposed to test memories. Compared with combinational and sequential circuits memory testing utilizes ...
متن کاملThe effects of exercising self-control on creativity
The purpose of this study is to examinewhether exercising of self-control improves creativity. Previous studies have indicated that promotion focus increases creativity; therefore, in Experiment 1, it had to be verified that exercising self-control could improve individual’s promotion focus. After confirming exercising self-control could improve promotion focus, it might indicate that exercisin...
متن کاملExercising self-control increases approach motivation.
The present research tested the hypothesis that exercising self-control causes an increase in approach motivation. Study 1 found that exercising (vs. not exercising) self-control increases self-reported approach motivation. Study 2a identified a behavior--betting on low-stakes gambles--that is correlated with approach motivation but is relatively uncorrelated with self-control, and Study 2b obs...
متن کاملExercising self-control increases relative left frontal cortical activation.
Self-control refers to the capacity to override or alter a predominant response tendency. The current experiment tested the hypothesis that exercising self-control temporarily increases approach motivation, as revealed by patterns of electrical activity in the prefrontal cortex. Participants completed a writing task that did vs did not require them to exercise self-control. Then they viewed pic...
