    摘要: An image processing apparatus capable of controlling the amount of codes in the image data of one image through one-pass encoding, without changing a quantization table. A Discrete Cosine Transformation (DCT) unit performs discrete cosine transformation on each MCU of the image data of the image. A quantizer quantizes DCT coefficients resulted from the discrete cosine transformation, using the quantization table. A code amount controller sets a threshold value for each MCU based on a target amount of codes for one image and the amount of codes usable for the unprocessed MCUs, reduces the quantized DCT coefficients based on the threshold value, in order to adjust the amount of codes to be generated in the MCU.

    摘要: A computer is made to execute the procedures of separating a hardware side from a software side within a reference source, and generating a merge model comprising a firmware interface for the software side to call the hardware side and comprising a hardware interface enabling an access to a mathematical function or a variable on the hardware side in response to a call from the firmware interface; and generating a system-on-chip (SoC) model comprising a CPU model for implementing a firmware interface with the software side, a hardware model for implementing the hardware side and a hardware interface connecting the CPU model to the hardware model.
