The arbiter block plays important role in the SoC shared bus communication. The masters on a SoC bus may issue requests simultaneously and hence an arbiter is required to decide which master is granted for bus access. Bus Arbiter plays a vital role in handling the requests from the master and responses from slave (like Acknowledgement signal, Retry, etc). The main objective of arbitration algorithms is to ensure that only one master has access to the bus at any given time, all the other masters are forced to remain in the idle state until they are granted the use of the bus.
