Метод формування енергоефективних кодів

Косенко, В.В.

The article considers the current problem of reducing the power that is dissipated in global communication lines while maintaining high performance. High switching activity leads to significant losses through coupling capacities between long lines. They are one of the most energy-intensive components of the embedded system. The use of Gray codes not only reduces dynamic energy losses in the address bus, but also minimizes communication losses between closely spaced lines. However, the Gray code has low balance and a large number of bit switches. The methods for constructing alternative Gray codes are investigated, which makes it possible to reduce the number of switches on the buses. The purpose of the article is to develop a method for constructing unit distance codes, determining the type of code transformations and forming a system of various typical representatives. Estimates of their number are obtained, characteristics are determined, catalogs of typical representatives are formed. The application of the developed method will make it possible to analyze and select codes with the best properties and, as a result, obtain the best results in terms of network delays, energy costs and other design constraints for computer systems.
