  • Patent number: 7079583
    Abstract: A media processing apparatus is made up of an I/O processing unit for performing input/output processing which asynchronously occurs due to an external factor and a decode processing unit for performing decode processing mainly for decoding of data streams stored in a memory in parallel with the input/output processing. The input/output processing includes receiving the data streams which are asynchronously inputted, storing the inputted data streams in the memory, and supplying the data streams from the memory to the decode processing unit. The decode processing unit is made up of a sequential processing unit mainly performing condition judgements on the data streams and a routine processing unit performing decode processing on compressed video data aside from header analysis of the compressed video data in parallel with the sequential processing.

  • Patent number: 7014228
    Abstract: A door closer includes a striker, a latch mechanism, and an actuator that brings the striker into a standby position when the actuator performs a standby action and, brings the striker into a closed position when the actuator performs a closing operation. After the striker is located at the standby position and engaged with the latch mechanism, the striker is moved to the closed position, thereby closing the trunk lid with respect to the vehicle body. Between the actuator and the striker, the striker is held at the standby position when the actuator performs the standby action in a normal state. When a switching operation is performed, the striker is allowed to move to the closed position even when the actuator 30 performs the standby action.

  • Patent number: 6809777
    Abstract: A pixel calculating device for performing vertical filtering that includes 16 pixel processing units 1 to 16 and an input buffer group 22 storing 16 pieces of pixel data and filter coefficients. Each of the pixel processing units performs operations using the pixel data and a filter coefficient supplied from input buffer group 22, and then acquires pixel data from an adjacent pixel processing unit. Further operations are performed by each of the pixel processing units using the acquired pixel data and operation results are accumulated. Filtering is carried out through a repetition of this acquiring and accumulation process, the number of taps being determined by the number of repetitions.

  • Publication number: 20030026487
    Abstract: The present invention provides an image decoding apparatus that realizes speed-up processing of taking out an MR (macroblock remainder) from a fixed length unit that consists of a first DCT block and the MR, without increasing cost. A Setup processor 3 outputs one out of a plurality of fixed length units that constitute an SB (synchronized block). First, calculation is performed for a length from a beginning of the fixed length unit to a EOB (end of block) that is included in the fixed length unit. The calculated length is then used as an offset in taking out the MR. Then an end portion of a second DCT block that is included in the MR is combined with a corresponding beginning portion of the second DCT block, in order to obtain the complete second DCT block. The complete second DCT block is outputted to a variable length code decoder 13.

  • Patent number: 6470376
    Abstract: The counter 52 is set with an initial value of “1” and is a counter with a maximum value of “4”. This counter 52 increments the count value held by the flip-flop 51 in synchronization with a clock signal so that the count value changes as shown by the progression 1,2,3,4,1,2,3,4. This clock signal is also used by the instruction decode control unit 11 to control the execution of instructions, with the counting by the counter 52 being performed once for each instruction execution performed by the instruction decode control unit 11. The comparator 54 compares the count value counted by the counter 52 with the maximum value “4”, and when the values match, sets the task switching signal chg_task_ex at a “High” value, so that the processing switches to the execution of the next task.
