17.7 Conclusion
• Hierarchy of performance models is proposed from the point of view of information processing.
• Shown that calculation of efficiency of computer system should include a role of
user and system software as well as hardware.
• Model of hardware from the point of view of information processing is
proposed.
• Calculation of performance of embedded system hardware is presented.
• Comparative study of proposed embedded architecture with most known
architectures is presented.
• Role of complexity of instruction set on performance is briefly discussed.
• Brief description of what kind of benchmarks is used for performance evaluation
of new and existing systems is presented.
• In details, using fence manufacture model shown that Amdahl Law is overoptimistic at an order of magnitude. It requires to consider the role of system
software and algorithms ability of parallel computing.
