Serial Architecture - a Modern Trend in the Field of Interface Development

Abstract

At the initial stages of computer technology development, preference in the field of interfaces was given to parallel data transfer, and an increase in the interface throughput was achieved by increasing its bit depth and operating frequency. However, at the current stage of interface development, there is an obvious tendency to replace parallel interfaces with serial ones.

The article examines the trends in the development of modern interfaces. A comparative analysis of modern parallel and serial interfaces is conducted. A conclusion is made about the feasibility of replacing both system and specialized single-wire interfaces with serial low-voltage differential interfaces.

Another trend in the development of modern interfaces is their unification and standardization. The article provides a corresponding example and indicates the restraining factors that prevent a reduction in the number of interfaces and, accordingly, simplification of the computer architecture.
