Self Checking Design Technique for Numerical Computations

Self-checking synchronous controller design

Efficient models are introduced for totally self-checking/code disjoint (TSCiCD) and strongly fault-secure/strongly code disjoint (SFS/ SCD) synchronous controller models. These models are based on two low-cost, modular, TSC edge-triggered and error-propagating CD flipflops. Properties of the proposed synchronous controller models are proven. The design procedure for these models and their prop...

A Numerical Design Technique for a Relay - Type Feedback Control System

An efficient numerical method for the design and synthesis of compensator for a relay type control system is developed and discussed. Previous works based on the interactive graphic method are reviewed and it is shown that the combination of the trequency and time domain numerical techniques provide a powerful tool in design of a wide class of relay control systems. An example is presented to d...

Numerical Computations of Self - Similarblow - up Solutions of Thegeneralized

The structure of the blow-up in nite time of a solution of the Generalized Korteweg-de Vries equation arising from a perturbed unstable solitary wave is studied numerically. The computed solution is observed to blow-up in the L 1-norm in nite time by forming a spike of innnite height at x = x and at t = t. Scaled coordinates are introduced to examine the detailed structure of the solution in th...

Self-Checking Design in Eastern Europe

LEADING VLSl CHIP and digital system manufacturers report an increasing number of undetected temporary faults that cause permanent damage in general-purpose microprocessor-based systems.’ Clearly, modern VLSI circuits require higher reliability as traditional means of protection against temporaiy faults become insufficient. This need renewed interest in self-checking circuits for on-line error ...
