摘要： PROBLEM TO BE SOLVED: To provide an image encoding device which does not necessitate reference of a quantization parameter between consecutive macro blocks across a parallel processing area without forming slices. SOLUTION: The image encoding device (1) encodes a macro block of an encoding target image by parallel processing sequentially from the top of a parallel processing area, and possesses each of encoding elements (120 to 122) for every parallel processing area. When all the quantized orthogonally-transformed coefficients of a top macroblock of the parallel processing area are zero, the encoding element adds a non-zero coefficient to a part of the coefficients, making the coefficients non-zero. Accordingly, generation of a skip macroblock in the top macroblock of each parallel processing area is suppressed. Since slice formation is not necessary, the prediction over a parallel processing area boundary is applied, and encoding efficiency improves. Errors are not generated in decoding and the decoded image quality does not deteriorate. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种图像编码装置，其不需要跨并行处理区域的连续宏块之间的量化参数的引用而不形成切片。解决方案：图像编码装置（1）通过从并行处理区域的顶部顺序并行处理对编码对象图像的宏块进行编码，并且对于每个并行处理区域具有编码要素（120〜122）。当并行处理区域的顶部宏块的所有量化的正交变换系数为零时，编码元件将一个非零系数加到系数的一部分，使系数不为零。因此，抑制了每个并行处理区域的顶部宏块中的跳过宏块的生成。由于不需要切片形成，因此应用了并行处理区域边界的预测，并且提高了编码效率。在解码中不产生错误，解码的图像质量不会恶化。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a microprocessor accompanied by a coprocessor which does not save a command address when an error occurs and execution command return control after completion of error processing.
SOLUTION: In a processor system, when an error detection unit 120 detects an error, it outputs an error signal to an interruption control unit 64. The control unit 64 outputs a value in an error address register 61 and a control signal to a program counter control unit 20, and achieves branch processing due to an error interruption by rewriting a value of a program counter 21 into the value in the register 61. When the error is detected, the system does not perform processing to save the value of the counter 21 when the error occurs, and is not provided with a control circuit for returning to a specified save register and to the command address at error occurrence after error processing.
