Abstract

A bus system, which may prevent data from being incorrectly transferred when an early termination occurs during a burst mode, may include a bus, for example, an advanced high-performance bus (AHB), at least one bus master device, a bus arbiter and at least one transfer mode selection circuit. The at least one bus master device may generate a burst cycle control signal, a transfer start signal and a bus control request signal for requesting control of the bus, and may be activated in response to a bus control grant signal, so as to exchange data via the bus. The bus arbiter may generate the bus control grant signal in response to the bus control request signal and provide the bus control grant signal to the bus master device. The at least one transfer mode selection circuit may convert a burst mode into a single mode to generate a selection signal, when the bus control grant signal is deactivated before a burst mode operation is completed.
