  • Publication number: 20090195542
    Abstract: 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.

  • Publication number: 20040091104
    Abstract: A parallel stream operation apparatus in which selecting keys for encrypting or decrypting stream data input in parallel is simplified. A plurality of paths that correspond respectively to a plurality of keys for encrypting and/or decrypting stream data are provided. Stream data received by a first interface is decrypted with a first decryption key, and stream data received by a second interface is decrypted with a second decryption key. An input stream processing unit outputs the stream data received by the first input unit to a first path corresponding to the first decryption key, and outputs the stream data received by the second input unit to a second path corresponding to the second decryption key. An operation unit decrypts the stream data from the first path with the first decryption key and the stream data from the second path with the second decryption key.

  • Patent number: 6728271
    Abstract: In a stream demultiplexing device, a synchronous clock signal is supplied to a header processing unit only when a header is being inputted and processed in the header processing unit, and supplied to a payload processing unit only when a payload is being inputted and processed in the payload processing unit. By such cutting off the synchronous clock signal supply to the header processing unit and the payload processing unit while they are not active, power consumption in the stream demultiplexing device is reduced.

  • Patent number: 6477606
    Abstract: 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.
