数控加工主轴转速，即在不同切深下所对应的主轴转速。-CNC machining spindle speed, that is, under different depth of cut corresponding to spindle speed.

5个源程序都是在VisualDSP环境下开发出来的，目标处理器是4片AD公司的TS1O1 DSP。其中：1）IDE_FAT32用来在硬盘上创建FAT32文件系统；2）i2c_test编写IIC总线；3）codec_a_in_pal_cf_frame是加载到FLASH的程序，板子在脱离PC自动上电时会把PAL制的图像直接存到CF卡里，CF卡的文件系统是FAT16；4）codec_a_in_pal_buf_boottest是可加载的DSP图像直通程序；5）ADSP-TS101prog_driver是flash的驱动程序。-five VisualDSP source in the environment are developed under the target processor is four AD TS1O1 the DSP. Of which : a) IDE_FAT32 used in the drive to create FAT32 file system; 2) to prepare i2c_test IIC bus; 3) codec_a_in_pal_cf_frame FLASH is loading procedures, the board automatically from the PC on when power will be PAL system images directly to CF card, the CF card is the FAT16 file system; 4) can be loaded codec_a_in_pal_buf_boottest DSP image through procedures; 5) ADSP-TS101prog_driver flash is the driver.

DM642的PROTEL封装库，及其开发板上其他元器件的封装，无需自己苦苦做库,极为难得。-DM642" s PROTEL package library, and the development of other components on-board package, hard to do without their own library, extremely rare.

示例说明：* 本示例初始化使用复杂的宏来配置缓存* L1、 L2 和 MAR 的双边投资条约，以提高性能的源代码* 位于外部内存中。为了说明性能增强，* 该示例使用 C674x DSP 库程序集函数* DSPF_sp_fftSPxSP 作为一个基准测试用例。DSP 功能进行了测试* 与禁用，随着 MAR 位集启用，L1 缓存* 和 MAR 位，L1 和 L2 启用。时钟周期数* 为计算每个条件下的函数将打印到控制台。
