System Services Overview
the core and system clock frequencies. When the application calls the
power management service to lower the operating frequencies, the power
management service automatically invokes the EBIU service, which
adjusts the SDRAM refresh rate to compensate for the reduced system
clock frequency.
Figure 1-1 illustrates the current collection of system services and the API
interactions among them.

With few constraints, applications can use any individual service
or combination of services within their application. Applications do not
have to all the services. Further, each service does not need all the
resources associated with the system that the service is controlling.
