APPLICATION OF PARETO ANALYSIS FOR QUANTITATIVE EVALUATION OF THE FREQUENCY OF COMPUTER COMMANDS USAGE
Annotation
The frequency of use of computer commands in implementation of three typical algorithms is analyzed. The object of the study is the command system of software model of a training computer. As an example, analysis of three programs in mnemonics is carried out, the programs correspond to three algorithms: a branching algorithm, an algorithm that handles elements of an array, and an algorithm using a subroutine. The established proportion of used and repeated commands in the process of solving problems confirms the validity and applicability of the principle "20/80" – the Pareto principle, which in the most general form can be formulated as "twenty percent of the efforts give eighty percent of the result, the remaining eighty percent provide only twenty percent of the result". Based on the results, the conclusion is made about the redundancy of the computer command system, leading to complication of the computer control device. As one of the possible ways to reduce the number of commands, it is suggested to reduce the conditional jump commands. The approach is supposed to provide a reduction in composition and structure of control devices of both hardware and firmware types.
