| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Computer systems are not only used in consumer electronics such as mobile phones and televisions but various industrial equipment such as a traffic control systems and medical devices.Space equipments and system which affecting human lives are required particularly high reliability.SVP (SuperVisor Processor) is a system for improving the reliability of the System.SVP guarantees the reliability of the system by the self-diagnosis and repair function.However, when the SVP fails, it cannot manage the system and becomes difficult to continuously operate the system.Therefore, we devide SVP function into 2-layered, Sys-SVP (System level SVP) and Hw-SVP (Hardware level SVP) to improve reliability.Sys-SVP is implemented in a part of processor core. and it manages and auxiliaries the entire system.Hw-SVP is implemented as a module with the highest reliability, and it tests, manages and recoveries the Sys-SVP.Hw-SVP is dependable due to its high reliability, and if failure occurs in Sys-SVP, Hw-SVP can recover it.In this way, SVP ensures high reliability to the system.In this paper, we consider the communication method to ensure reliability in the two-layered SVP.Then, we make a communication test between implemented Hw-SVP and pseudo Sys-SVP which is implemented on the PC.We confirm Hw-SVP working correctly from the test results. | |
