Description

High-speed networks are employed in industrial systems, which affect real-time processing such as motor control. We propose a SoC architecture for industrial controllers to reduce the network protocol processing load. We adopt a RTOS in hardware in order to accelerate RTOS execution. The hardware RTOS and the CPU are connected by loosely coupled interface to use ARM processor as the core. We manufactured the SoC for industrial controllers using the proposed architecture. The results of our experimental evaluations showed that the API execution time was 1.4-2.9 times faster compared with that when using a conventional software RTOS.
