摘要： In an image processing apparatus using a read buffer, in a case where access request target data is not stored in the read buffer, the read buffer is controlled such that data corresponding to a position having coordinates, which is most distant from a position having coordinates corresponding to the access request target data, is discarded or replaced. Consequently, the image processing apparatus increases the probability that data corresponding to a position close to a position corresponding to the access request target data remains in the read buffer. Accordingly, the hit rate of the read buffer is increased. Thus, the frequency of access to an external memory can be reduced.

摘要： A master device in a system including a bidirectional bus and at least one device manages whether the system is in an access state in which the master device permits an access to or from one device or a non-access state in which the master device permits an access to none of the devices. The master device drives the bidirectional bus using a predetermined current to transfer data to or from one device connected to the bidirectional bus when the system is in the access state. When the state of the system changes from the access state to the non-access state, the master device drives the bidirectional bus in order to stabilize the potential of the bidirectional bus to keep the bus potential from changing when the system is in a non-access state, thereby eliminating the need for conventional pull-up/pull-down resistors for stabilizing the bus potential during a non-access state.
