Abstract

A description is given of a real-time operating system (RTOS) which can allow users to achieve the gradual migration from the ITRON kernel to the μITRON kernel. It has some risks for the user to migrate between the two ITRONs because each kernel has a different system call specification. The μITRON promises speed. The ITRON, on the other hand, provides functionality to make robust programs managing complex application areas. The authors are successfully developing a novel RTOS which has two system call interfaces for the user migration between the two ITRONs with no risk. This RTOS allows users to achieve functional migration from the ITRON to the μITRON while using the ITRON interface and almost achieving the μITRON speed
