Abstract

In embedded application fields, the operating system presentes the more stern reality demand such as reconstruction, expansion, transplantation, interaction, security, and efficient. In combination with the above features of embedded system and inherent characteristics of Forth systems, using Forth virtual machine technology, this paper explored the key techno-logies of embedded operating system based on Forth virtual machine architecture, and proposed an embedded multitask opera-ting system scheduling algorithm based on Forth virtual machine architecture, which had better extension and transplantation characteristics. The algorithm adopted a cooperative multi-task scheduling mechanism with Forth virtual machine instruction synchronization, shortened the task switching time, and simplified context switching operations to simply saving the data stack pointer. The experiment results demonstrate that the multitask scheduling algorithm based on Forth virtual machine architecture develops the inherent characteristics of Forth system, presents higher efficiency for specific applications, especially benefits for embedded environments with limited resources.
