A bus request includes mode information for selecting that error notification for an access is performed by the bus slave or the bus master. In a case where the mode information indicating that error notification is performed by the bus slave is included in the bus request, when an error for an access in that bus request has occurred, the bus slave performs error notification. In a case where execution of an instruction of a speculative load access has been fixed and error information for the load access has been received from the bus slave, the bus master performs error notification based on the error information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data access device and access error notification method","description":"Error notification by a bus master for a speculative access and error notification by a bus slave for a non-speculative access are achieved while a circuit scale of the bus master is suppressed.
