The document discusses improvements that can be made to the bus master grant signals in an AMBA 2.0 specification compliant AHB system. Specifically, it proposes: 1. Having the arbiter include a decoder that identifies the requesting master after receiving a bus request, and outputs the master ID and a grant signal. 2. The grant signal and master ID are multiplexed to determine which master is granted access and drive the address/control lines. 3. Control signals like burst and transfer types are connected to both the slave and arbiter for arbitration, and there is multiplexing of response signals from the slave.
