Methods for Increasing the Perfomance of Co-Emulation of Computing Systems on the Example of the Sce-Mi Standard Realization

This work is devoted to the implementation of one of the ways to organize co-emulation between models of digital electronic devices written using hardware description languages and higher-level systems. The work is based on the open co-emulation standard SCE-MI. This paper considers the main modern approaches to the emulation of computing systems and the tasks whose solution is required to organize the process of co-emulation. Some features of the Semi standard and modeling tools that have an effect on the modeling performance of the final system are described. The implementation of the standard offers its extensions that allow using the resulting solution as part of low-level software. Examples of using the developed solution as a part of Qemu emulator and a loadable kernel module of the Linux operating system are given.
