INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM

An information processing device is employed in a vehicle control system and controls access to a shared storage. The information processing device includes a memory and a processor. The processor creates multiple threads. The processor stores, in the memory, access requests for access to the shared storage by applications and adds the access requests for access to a queue such that the access requests are lined up before proceeding with processes in the applications. The processor executes the access requests lined up in the queue using free threads in the order in which the access requests were added to the queue.
