INFORMATION PROCESSING APPARATUS AND ERROR PROCESSING

An information processing apparatus includes a first processing unit, a second processing unit, and a common storage unit that is commonly accessed by the first processing unit and the second processing unit. The first processing unit writes a request in the common storage unit for requesting the second processing unit to perform a certain process, and notifies the second processing unit of the request. The second processing unit writes a notification in the common storage unit indicating the process is completed in response to the request.
