Issues of compatibility of processor command architectures

Abstract

Modern computers and computing devices are based on the principle of open architecture, according to which the computer consists of several sufficiently independent devices that perform a certain function. These devices must meet certain standards of interaction with each other. Existing standards relate to both the technical characteristics of the devices and the content of the signals exchanged between them. The article considers the issue of creating a universal architecture of processor commands. The brief analysis of the components of devices and interrelations between them (different hardware features of processors, architecture of memory models and registers of peripheral devices, mechanisms of operand processing, the number of registers and processed data types, interruptions, exceptions, etc.) is carried out. The problem of architecture standardization, which generalizes the capabilities of the most common architectures and is suitable for high-performance emulation on most computer architectures, is put. © Published under licence by IOP Publishing Ltd.
