摘　　要：An increasing number of tasks now require the use of hardware accelerators to reduce the time required for computation and display the computational results.This paper presents a new graphics system architecture for operating systems(OSs)with microkernel architecture,including real-time OSs.The proposed system architecture provides capabilities for displaying graphical images on various information display devices and for accelerating graphical operations on GPU.The architecture of the graphics system uses a concept of allocators to manage system and video memory,provides an abstraction of memory operations with a single interface for video memory management,and simplifies memory handling where incorrect operation is the cause of many failures.A comparison between the performance of a real-time OS and Linux OS implementing the graphics system using the example of a glmark2 benchmark is presented,thereby the superiority of the proposed architecture in several scenarios is demonstrated.
