An Approach to Advance Real-Time Os Services with Soft-Error

Swapan Debbarma

Abstract—the rises of RTOSs have evolved from single-use specialized systems to a wide of more general purpose Operating Systems (such as real-time variants of Open Source Operation System. These-days, numbers of critical applications that have stringent real-time constraint are placed and run in an environment with Real-Time operating system (RTOS). The provided services of RTOSs are subject to faults that affect both functional and timing of Tasks which are running based on RTOS. In this paper, we try to evaluate and analyze robustness of services due to soft-errors in two proposed architecture of RTOS which are (SW-RTOS and HW/SW-RTOS). Accordingly, we propose for an architecture which provides more robust services in term of soft-error. Real-Time Operating System (RTOS) users desire predictable response time at an affordable cost, due to this demand Hardware/Software Real-Time Operating Systems (HW/SWRTOS) appeared. This paper analyzes the impact of softerrors in real-time systems running applications under purely Software RTOS versus HW/SW-RTOS. The proposed model is used to evaluate robustness of services like scheduling, synchronization time management and memory management and inter process communication in Software based RTOS and HW/SW-RTOS. Experimental results show HW/SW-RTOS provide more robust services in term of soft-error against purely software based RTOS.
