Abstract: An intelligent power control peripheral (IPCP) may facilitate communications among individual peripherals independent from a digital processor. The IPCP is a "Meta-Peripheral" that may incorporate a configurable inter-peripheral module communications network with digital pulse width modulation (PWM) generators and timing logic therefore, at least one ADC, analog comparators and at least one DAC that may be configured to provide an automatic power control structure that may also provide automatic digital processor/DSP task and workload scheduling for applications such as switch mode power supply (SMPS), brushed motor, etc. This Meta-Peripheral may further use a configurable control fabric in combination with the aforementioned specialized peripherals for the utmost in control configuration flexibility.

Abstract: A pulse width modulation (PWM) generator having asynchronous updating of its PWM duty cycle and/or period values allows immediate correction for the new PWM duty cycle and/or period values instead of waiting until the end of a PWM period to accept the new duty cycle and/or period values. This reduces the latency in a control loop when responding to changing system status, e.g., changes in PWM duty cycle. Also the PWM duty cycle is prevented from "running away" (e.g., missing a PWM cycle) if the PWM duty cycle timer/counter has advanced beyond an updated duty-cycle maximum value.

Abstract translation: 具有其PWM占空比和/或周期值的异步更新的脉宽调制（PWM）发生器允许立即校正新的PWM占空比和/或周期值，而不是等待直到PWM周期结束才接受新的占空比 周期和/或周期值。 当响应改变的系统状态时，这减少了控制回路中的等待时间，例如，PWM占空比的变化。 而且，如果PWM占空比计时器/计数器超前于更新的占空比最大值，则PWM占空比被防止“逃跑”（例如，丢失PWM周期）。
