In recent embedded real-time systems, there are many systems with both hard real-time tasks and soft real-time tasks. While a soft real-time task has a low priority and its throughput is important, a hard real-time task has a high priority and is executed in a short period. In this paper, we propose a low latency real-time execution mechanism which separates a hard real-time task with a high priority from the real-time scheduler and executes that task in a shorter period. We implement this mechanism by use of Dependable Responsive Multithreaded Processor. At the same time, low priority tasks are scheduled by the real-time scheduler, and hence the entire throughput is maintained. In our experimental evaluation, the low latency real-time execution mechanism executes a task in the period of 50 μs, and hence we show that its overhead and jitter are enough small. |
