    • A method, computer-readable medium, and apparatus for debugging a computer program utilizing breakpoints triggered by accessing a rarely used or unused I/O port is provided. Rarely used or unused I/O ports are identified in a computer system and a debugger program is instructed to halt program execution when an access is made to one or more of the identified ports. An instruction for writing to one of the ports is then inserted in the program to be debugged. When the instruction is executed, the debugger program will cause the execution of the program to stop. When the breakpoint is no longer needed, the debugger program is instructed not to halt when an access is made to the I/O port.
    • 提供了一种利用通过访问很少使用或未使用的I / O端口触发的断点来调试计算机程序的方法,计算机可读介质和装置。 在计算机系统中识别出很少使用或未使用的I / O端口,并且当对一个或多个所识别的端口进行访问时,指令调试器程序停止程序执行。 然后将一个写入其中一个端口的指令插入到要调试的程序中。 当指令执行时,调试器程序将导致程序的执行停止。 当不再需要断点时,指示调试程序在I / O端口访问时不停止。

    • Design variable value sets for predetermined design variables are generated, and for each of the predetermined design variables, parameter value sets for predetermined parameters are generated. For each combination of them, circuit simulation is carried out to obtain a performance item value set for predetermined performance items. Then, for each of the design variable value sets, and further for each of the parameter value sets generated for a corresponding design variable value set, combinations of the design variable value set and parameter value set are identified, for which performance item values for all of the predetermined performance items are not less than performance item values obtained for a combination of the corresponding design variable value set and a corresponding parameter value set, and a yield rate is calculated by dividing the number of identified combinations by the number of parameter value sets generated for the corresponding design variable value set.

    • The present invention relates to method and apparatus for video coding by ABT-based just noticeable difference (JND). For building the just noticeable difference model, spatial content information (SCI) is used to represent the spatial appearance similarity between one macroblock and its sub-blocks and the motion characteristic distance (MCD) is used to represent the motion characteristics similarity between one macroblock and its sub-blocks. For intra frames, the balance strategy based on the obtained SCI of the macroblock is used to generate the ABT-based JND model. For inter frames, the balanced strategy based on the obtained SCI and MCD of the macroblock is used to generate the ABT-based JND model. Using the ABT-based JND model, the residual coefficients for each block in a frame is filtered to obtain a reduced set of residual coefficients for transmission without degradation in visual quality.
    • 本发明涉及基于ABT的仅显着差异(JND)的视频编码方法和装置。 为了构建正确的差异模型,使用空间内容信息(SCI)来表示一个宏块与其子块之间的空间外观相似度,运动特征距离(MCD)用于表示一个宏块与 其子块。 对于帧内帧,使用基于获得的宏块的SCI的平衡策略来生成基于ABT的JND模型。 对于帧间帧,使用基于获得的宏块的SCI和MCD的平衡策略来生成基于ABT的JND模型。 使用基于ABT的JND模型,对帧中的每个块的残差系数进行滤波以获得用于传输的残差系数的减少集,而不会降低视觉质量。
