COM-EXPRESS MODULES BASED ON ELBRUS MICROPROCESSORS FOR ONBOARD COMPUTING SYSTEMS

Abstract

Research in the field of creating specialized computing systems for robots is conducted in many world scientific centers, including our country. The development of capabilities of sensor systems, global navigation systems, growth of computing power and improvement of algorithms allow creating onboard computing systems with broad intellectual capabilities. An important, but unsolved problem remains the equipping of such computing systems with domestically produced microprocessors. The need to take into account the maximum weight and size characteristics, the requirements for the cooling system of the computing complex, the requirements for on-boardpower supply and power consumption, performance requirements and external interfaces cause the complexity and high cost of developing on-board computing systems. The lack of unification of computing modules during development creates additional difficulties for developers of robots, increases the final cost of the robot and complicates its modernization. The use of a standardized form factor such as COM-Express makes it possible to divide the onboard computing complex into a universal high-tech system part and a carrier board. The microprocessor, peripheral interface controller, RAM and hard disk are placed on the system module, which is produced in large quantities and can be replaced with a newer one when new generations of domestic computing equipment appear. The carrier board, in turn, is easy to develop and cheap to manufacture, and according to its characteristics can be configured for a specific robotic complex. This article discusses COM-Express modules based on domestic Elbrus microprocessors. Their applicability for the creation of promising on-board computing systems is shown. The results obtained by the authors indicate the prospects of import substitution in the field of robotics.
