1756-OW16IA A-B 控制系统 渠道优势

A-B 1756-OW16I 进入深度休眠状态后，耗电量会降低，但进入这种状态和恢复的处理会临时消耗多余的电力。新技术可根据定时器的设定值来推测空闲时间，如果空闲时间长于损益平衡点（约13ms），就会选择深度休眠。而且，还通过优化程序，缩短了进入深度休眠和恢复到工作模式的处理时间。

要进行项判断的原因是，如果SoC在存储器或显示器的控制器等的输入输出电路正在工作时进入深度休眠，就会发生严重的错误。对此，东芝采用了一种机制，那就是在要求输入输出电路进行处理时，将标志位设为True，当接收到用来通知处理完成的中断时，再将标志位设为False。这样，OS便可以立即判断出输入输出电路是否正在工作。

The A-B 1756-OW16I consumes less power when it enters deep sleep, but the processing to enter this state and recover temporarily consumes excess power. The new technology can predict the idle time based on the set value of the timer, and if the idle time is longer than the break-even point (about 13ms), deep sleep will be selected. Moreover, the processing time for entering deep sleep and returning to working mode is shortened by optimizing the program.

The reason for this judgment is that if the SoC goes into deep sleep while the input and output circuits of the memory or the controller of the display are working, a serious error can occur. To this end, Toshiba has adopted a mechanism that sets the flag bit to True when processing is requested from the input/output circuit, and False when an interrupt is received to notify that processing is complete. In this way, the OS can immediately determine whether the input and output circuits are working.
