摘要： An integrated circuit for a modem processor includes processing units that are partitioned into "always-on" and "collapsible" power domains. An always-on power domain is powered on at all times. A collapsible power domain can be powered off if the processing units in the power domain are not needed. A power control unit within an always-on power domain powers down the collapsible power domains after going into sleep and powers up these domains after waking up from sleep. Tasks for powering down the collapsible power domains may include (1) saving pertinent hardware registers for these power domains, (2) freezing output pins of the IC to minimally disturb external units, (3) clamping input pins of the collapsed power domains, (4) powering down a main oscillator and disabling the oscillator clock, and so on. Complementary tasks are performed for powering up the collapsed power domains.
摘要翻译：用于调制解调器处理器的集成电路包括被划分为“永远在线”和“可折叠”电力域的处理单元。永远在线的电源域始终打开。如果不需要电源域中的处理单元，则可以关闭可折叠电源域。永远在线的电源域内的电源控制单元在睡眠后唤醒可折叠的电源域，并在从睡眠中唤醒之后启动这些域。关闭可折叠电源域的任务可能包括（1）保存这些电源域的相关硬件寄存器，（2）冻结IC的输出引脚以最小限度地干扰外部单元，（3）钳位崩溃的电源域的输入引脚（ 4）关闭主振荡器并禁用振荡器时钟，等等。执行补充任务以加电折叠的电源域。
