    • The present invention provides a method and system to improve the cookbook search algorithm used in a coding/decoding device or routine. The codebook search algorithm is performed by a processing system that allows for parallel execution of instructions, for example a DSP. An embodiment of the present invention provides a method for coding of a first waveform. First a plurality of vectors determined from a plurality of waveforms is stored in a memory. Next a minimum weighted error using a plurality of filter coefficients and the plurality of vectors is determined. The minimum weighted error gives a closest match between the first waveform and a second waveform synthesized from a selected vector of the plurality of vectors. Then an indication of said selected vector is provided as part of a code of the first waveform. The plurality of filter coefficients have added to them at least one duplicate filter coefficient such that the performance of determining the minimum weighted error is improved, by for example, at least one clock cycle.
    • 本发明提供了一种改进在编码/解码装置或程序中使用的食谱搜索算法的方法和系统。 码本搜索算法由允许并行执行指令的处理系统执行,例如DSP。 本发明的实施例提供了一种用于编码第一波形的方法。 首先,从多个波形确定的多个向量存储在存储器中。 接下来,使用多个滤波器系数进行最小加权误差,并确定多个向量。 最小加权误差给出了第一波形与从多个向量的选定向量合成的第二波形之间的最接近的匹配。 然后,提供所述选择的向量的指示作为第一波形的代码的一部分。 多个滤波器系数已经向它们添加了至少一个重复滤波器系数,使得通过例如至少一个时钟周期来改善确定最小加权误差的性能。

    • A method and apparatus for re-generating debug commands is provided comprising a source program having embedded debug commands in a first distinguishable field, and an assembler. The assembler operates on the source code extracting the embedded debug commands and associated address information from the source code while generating object code. The debug commands are stored in a command file for use during simulation. A simulator executes the assembled object code in conjunction with a debugger which executes the stored debug commands as designated during the execution cycle. Upon the termination of a simulation run and the subsequent modification of the source program, the debug commands are automatically re-generated with correct addresses as determined during the subsequent assembly. When the edited source file is loaded, the break-points are cleared and a new command file is executed to insure that the break-points are relocated to the correct source lines. The execution of the embedded debug commands can be enabled or disabled by means of a command line option, so when the debugging is complete, the debug information will not be outputted.
    • 提供了一种用于重新生成调试命令的方法和装置,包括在第一可区分字段中具有嵌入式调试命令的源程序和汇编器。 汇编程序对源代码进行操作,从源代码中提取嵌入式调试命令和关联的地址信息,同时生成目标代码。 调试命令存储在命令文件中,以便在仿真期间使用。 模拟器与执行在执行周期中指定的存储的调试命令的调试器一起执行组装的目标代码。 在模拟运行结束和源程序的后续修改之后,将在随后的组装过程中确定的正确地址自动重新生成调试命令。 当编辑的源文件被加载时,断点被清除,并且执行新的命令文件以确保断点被重定位到正确的源行。 可以通过命令行选项启用或禁用嵌入式调试命令的执行,所以调试完成后,调试信息将不会被输出。
