`

`BACKGROUND
`
`Field of the Invention
`
`[0001]
`
`This invention is related to the field of systems including processors and
`
`5
`
`peripheral devices, and managing power consumption in such systems.
`
`Description of the Related Art
`
`[0002]
`
`As the number of transistors included on an integrated circuit "chip" continues
`
`to increase, power management in the integrated circuits continues to increase in
`
`10
`
`importance. Power management can be critical to integrated circuits that are included in
`
`mobile devices such as personal digital assistants (PDAs), cell phones, smart phones,
`
`laptop computers, net top computers, etc. These mobile devices often rely on battery
`
`power, and reducing power consumption in the integrated circuits can increase the life of
`
`the battery. Additionally, reducing power consumption can reduce the heat generated by
`
`15
`
`the integrated circuit, which can reduce cooling requirements in the device that includes
`
`the integrated circuit (whether or not it is relying on battery power).
`
`[0003]
`
`Clock gating is often used to reduce dynamic power consumption in an
`
`integrated circuit, disabling the clock to idle circuitry and thus preventing switching in
`
`20
`
`the idle circuitry. Additionally, some integrated circuits have implemented power gating
`
`to reduce static power consumption ( e.g. consumption due to leakage currents). With
`
`power gating, the power to ground path of the idle circuitry is interrupted, reducing the
`
`leakage current to near zero.
`
`25
`
`[0004]
`
`Clock gating and power gating can be effective power conservation
`
`mechanisms. However, in some cases, these mechanisms are not as effective as desired.
`
`For example, systems that include processors can cause the processors to enter a sleep
`
`state to conserve power. Whle the processor is in sleep state, other components in the
`
`system are still active, and often are operating at performance levels that support the
`
`30
`
`active processors. When the processors are in the sleep state, these other components
`
`1
`
`Qualcomm, Ex. 1007, Page 16
`
`

`

`need not be operating at such a high performance level. Similarly, when the processors
`
`are awakened from the sleep state, the performance level at which the processors and
`
`other components need to operate to support the activities being performed by the system
`
`may be different than the performance level prior to the processor entering the sleep
`
`5
`
`state.
`
`[0005]
`
`The sleep/wake transitions of the processors and other components are
`
`changed under software control. The software executes on the processors, and thus
`
`changing the performance levels of the processors and other components can affect the
`
`10
`
`amount of time required to execute the software. These effects impact the efficiency of
`
`the transition, impacting the power conserved and the performance of the application.
`
`Furthermore, the software execution time can affect how often the processor is
`
`transitioned to the sleep state, and the amount of reduced performance that can be
`
`tolerated in the rest of the system.
`
`15
`
`SUMMARY
`
`[0006]
`
`In an embodiment, a power management unit may be configured to
`
`automatically transition (in hardware) the performance states of one or more performance
`
`20
`
`domains in a system. The target performance states to which the performance domains
`
`are to transition may be programmable in the power management unit by software.
`
`Additionally, the software may signal the power management unit that a processor in the
`
`system is to enter the sleep state. Alternatively, the power management unit may monitor
`
`the processor to detect tha thte processor is entering the sleep state or has entered the
`
`25
`
`sleep state. The power management unit may be configured to control the transition of
`
`the performance domains to the target performance states, and may also cause the
`
`processor to enter the sleep state in some embodiments. In an embodiment, the power
`
`management unit may be programmable with a second set of target performance states to
`
`which the performance domains are to transition when the processor exits the sleep state.
`
`30
`
`The power management unit may be configured to control the transition of the
`
`2
`
`Qualcomm, Ex. 1007, Page 17
`
`

`

`performance domains to the second targeted performance states and may also cause the
`
`processor to exit the sleep state in some embodiments.
`
`[0007]
`
`In one embodiment, the transition of the performance domains into different
`
`5
`
`target states may be more rapid when controlled by the power management unit than may
`
`be possible with software control. Accordingly, the power conservation may be more
`
`efficient that a purely software-controlled implementation, and the performance of
`
`applications executing in the system may also be positively affected. Additionally, the
`
`configureability of the performance states may permit more fine-grained control of the
`
`10
`
`performance level in the system and thus may permit additional power savings. In some
`
`cases, the performance states may be reduced further than would be possible in the
`
`software-controlled implementation, because the time required for the software to
`
`execute while the system is in the lower performance states is a reduced factor ( or may
`
`even be eliminated).
`
`15
`
`[0008]
`
`Each component of the system may be included in a performance domain, and
`
`each performance domain may include at least one component but may include multiple
`
`components, in various embodiments. The power management unit may be
`
`programmable with performance state identifiers for each performance domain, and for
`
`20
`
`each hardware-managed transition ( e.g. into the sleep state, out of the sleep state, or both
`
`into and out of the sleep state, in various embodiments). The sleep state of the processor
`
`may also be a performance state, as may various other performance states that the
`
`processor may be programmed to in various embodiments.
