摘要：
This paper presents a real-time operating system (RTOS) that supports location-transparent shared resource management for multi-core embedded control systems. We modify the Multiprocessor Stack Resource Policy (MSRP) for the fixed priority scheduling of OSEK OS and extend an OSEK OS to provide location-transparent resource management based on the modified MSRP. Application tasks access local (intra-core) shared resources and inter-core shared resources using the same system calls. The RTOS also provides location-transparent inter-core and inter-node task management and event control. We have also confirmed that the performance of the RTOS is acceptable for practical embedded control systems.
