    摘要: An apparatus and method for adaptively changing clock frequencies of a Central Processing Unit (CPU) and a bus in a digital system are provided. The system includes an Adaptive Frequency Scaling (AFS) controller and a clock controller. The AFS controller determines whether to change a clock frequency of the CPU according to operation information of the CPU, and determines whether to change a clock frequency of the bus according to operation information of the bus. The clock controller generates a clock frequency of the CPU and a clock frequency of the bus according to the determination of the AFS controller.

    摘要: An apparatus and a method for writing bitwise data in a System On Chip (SOC) are provided. In the method, a master determines whether a size of data to be written on a slave is equal to or smaller than half of a size of data transmittable at a time. If it is determined that the data is equal to or smaller than half of the size of the data transmittable at a time, the master transmits the data to the slave via a bus. The master transmits a signal representing a bit at which the data is to be written via a bus lane not used for the data transmission.
