  • Publication number: 20060242387
    Abstract: In order to overcome the problem that conditionally executed instructions are executed as no-operation instructions if their condition is not fulfilled, leading to poor utilization efficiency of the hardware and lowering the effective performance, the processor decodes a number of instructions that is greater than the number of provided computing units and judges their execution conditions with an instruction issue control portion before the execution stage, Instructions for which the condition is false are invalidated, and subsequent valid instructions are assigned so that the computing units (hardware) is used efficiently. A compiler performs scheduling such that the number of instructions whose execution condition is true does not exceed the upper limit of the degree of parallelism of the hardware. The number of instructions arranged in parallel at each cycle may exceed the degree of parallelism of the hardware.

  • Patent number: 6510250
    Abstract: A decoder decodes encoded binary image data on each block in order to recover a target block of the binary image. The image decoder includes motion compensated blocking which obtains a reference block from a reference binary image by applying motion compensation using motion information. A selector selects a statistical model from among a plurality of statistical models, based on states of pixels surrounding a reference pixel in the reference block, in which the reference pixel also corresponds to a target pixel in the target block. An arithmetic decoder recovers the target block by decoding the encoded data using the selected statistical model. In one embodiment, the pixels surrounding the reference pixel in the reference block are pixels positioned within one pixel distance from the reference pixel.

  • Publication number: 20010019546
    Abstract: In the CDMA Radio Multiplex Tansmission, transfer function of line is inferred by using common pilot signal and sychronous detection is performed accordingly. The transmitting end transmits by periodically inserting pilot symbols into one channel only of multiplexed channels. The receiving end infers line condition (transfer function) from the received pilot symbols and, on the basis of the information thus obtained, performs synchronous detection of each channel multiplexed.

  • Patent number: 6233251
    Abstract: A multiplex frame is of a fixed length and includes a header and a fixed-length field. The fixed-length field is divided into variable-length slots 1 and 2. The length of the variable-length slot 1 is a predetermined fixed length when data to be stored exists and is zero with no data to be stored. The length of the variable-length slot 2 is increased/decreased depending on the length of the variable-length slot 1. Fixed-length data not employing retransmission (e.g., an audio frame) is transmitted in the first variable-length slot and one complete variable-length data employing retransmission (e.g., a data link frame of video) is transmitted in the second variable-length slot.

  • Patent number: 5677935
    Abstract: A sync pattern detecting circuit detects a sync pattern from the input data to output a sync pattern detecting signal. A frame counter counts clock signals for the bit number of one frame to output a frame count signal. A sync manage circuit sets a window time area therein, and outputs a sync signal when the sync pattern detecting signal is input in the window time area. The width of the window time area is variable. The width of the window time area is controlled at timings at which the sync pattern detecting signal and the frame count signal are input.
