NI PXI-5441任意波形发生器中文资料：
NI PXI-5441任意波形发生器从CPU固件9.0版开始，350–364 CPU组中的所有其他CPU都提供了基于固件的浮点运算功能。尽管CPU352和CPU374的基于硬件的浮点运算与基于固件的类型之间存在速度差异，但这对许多用户来说并不重要。对于需要更快性能的应用，CPU352和CPU374是最佳选择。浮点数学指令在GFK-0467K或更高版本的Series 90-30 PLC CPU指令集参考手册中进行了解释。闪存所有350–374个CPU都内置闪存，有两个用途：Ŷ它提供CPU固件的非易失性存储。NI PXI-5441它为您提供了在非易失性闪存中存储程序、配置和寄存器数据的选项。使用此内存的两种方法是：（1）存储用户内存的板载备份副本（尽管我们仍然建议您保留完整程序文件夹的单独备份副本），以及（2）以无电池模式运行。有关详细信息，请参见第6章。NI PXI-5441
英文资料
Starting with CPU firmware release 9.0, all of the other CPUs in the 350–364 CPU group were provided with firmware-based floatingpoint math capability. Although there is a speed difference between the hardware-based floatingpoint math of the CPU352 and CPU374 and the firmware-based type, this will not be significant to many users. For applications where faster performance is important, the CPU352 and CPU374 are the best choice. The floating-point math instructions are explained in the Series 90-30 PLC CPU Instruction Set Reference Manual, GFK-0467K or later. Flash Memory All of the 350–374 CPUs have built-in Flash memory, which serves two purposes: Ŷ It provides non-volatile storage of the CPU firmware. Ŷ It gives you the option of storing program, configuration, and register data in non-volatile Flash memory. Two ways of using this memory are: (1) to store an on-board backup copy of user memory (although we still recommend that you keep a separate backup copy of your complete program folder), and (2) for running in a battery-less scheme.
