Raspberry Pi is an optional and popular solution in building the EPICS Input/output Controller (IOC) owing to its high flexibility, expansion capability and affordability. However, the requirement of the device real time capability is critical in the SuperKEKB accelerator since the special demand of the timing system. To assess the possibility of Raspberry Pi based IOC within a 50 Hz beam repetition rate, we perform a latency test on the Raspberry Pi and compare the standard kernel and real time kernel.
