NI PXI-5441任意波形發(fā)生器中文資料：
NI PXI-5441任意波形發(fā)生器從CPU固件9.0版開始，350–364 CPU組中的所有其他CPU都提供了基于固件的浮點(diǎn)運(yùn)算功能。盡管CPU352和CPU374的基于硬件的浮點(diǎn)運(yùn)算與基于固件的類型之間存在速度差異，但這對許多用戶來說并不重要。對于需要更快性能的應(yīng)用，CPU352和CPU374是最佳選擇。浮點(diǎn)數(shù)學(xué)指令在GFK-0467K或更高版本的Series 90-30 PLC CPU指令集參考手冊中進(jìn)行了解釋。閃存所有350–374個(gè)CPU都內(nèi)置閃存，有兩個(gè)用途：?它提供CPU固件的非易失性存儲(chǔ)。NI PXI-5441它為您提供了在非易失性閃存中存儲(chǔ)程序、配置和寄存器數(shù)據(jù)的選項(xiàng)。使用此內(nèi)存的兩種方法是：（1）存儲(chǔ)用戶內(nèi)存的板載備份副本（盡管我們?nèi)匀唤ㄗh您保留完整程序文件夾的單獨(dú)備份副本），以及（2）以無電池模式運(yùn)行。有關(guān)詳細(xì)信息，請參見第6章。NI PXI-5441
英文資料
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: ? It provides non-volatile storage of the CPU firmware. ? 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.
