Using Information Theory to Study Efficiency and Capacity of Computers and Similar Devices

We address the problem of estimating the efficiency and capacity of computers. The main goal of our approach is to give a method for comparing the capacity of differentcomputers, which can have different sets of instructions, different kinds of memory, adifferent number of cores (or processors), etc. We define efficiency and capacity ofcomputers and suggest a method for their estimation, which is based on the analysis ofprocessor instructions and their execution time. How the suggested method can be applied toestimate the computer capacity is shown. In particular, this consideration gives a new lookat the organization of the memory of a computer. Obtained results can be of some interestfor practical applications
