Abstract
A bus system includes one or more bus masters, one or more bus slaves, and a response unit. When an access request to a resource of a bus slave is sent from a bus master, the response unit outputs a wait response that is either a blocking wait response to cause the bus master to perform a blocking wait operation or a non-blocking wait response to cause it to perform a non-blocking wait operation to the bus master if the bus slave is in the wait state.
