The Way

The models, methods and means as target resources for solving tasks for design and testing of computer systems and their components are considered. A criterion for choosing the target resources activating the natural resources for the increasing the efficiency of task solutions is determined. A problem of low checkability of digital components of safety-critical systems is examined and the ways of its solution is showed by choosing the target resources in accordance with the offered criterion. The way of elimination of a contradiction between the target resources aimed to maintain the checkability, productivity and low complexity of digital components is described. This way is based on parallelization of computations with the use of the serial codes.

Two Sides

Technology is growing very fast with various changes in Computer Systems. They are chasing human life. They are used in various fields around us. There are some governments who fund for computer systems. Still research related them is carry on and will carry. Mostly there services are used in defense purpose. Based on computer technology there are so many improvement in them, even embedded system are developed. Any system can present some risk to its owner’s, users and environment. Risk is based on low and high. Some systems present more risk than others. Those which are related to more risk are called safety-critical systems. Safety critical systems are categorized into dangerous systems whose failures could result in loss of life, loss of revenue, knowing them and unable to solve them is sabotage to property damage or damage to the environment. This paper focus better exercises for making good user-friendly software. Every system has two sides as if coin, one side is the physical system with hardware and other side is software. If anything is neglected, there is a chance of bug appears at run-time. This may cause loss to humans. Again a committee report will be preserved for future purpose.
