Abstract:
1. A method, comprising: receiving a request originated by a software unit, wherein the software unit implements non-runtime control of a system embodied in an integrated circuit, and wherein the request is received at a hardware unit implementing runtime control of the system, the received request identifying at least one operating point for a subsystem of the integrated circuit, the operating point being chosen from among a plurality of operating points, at least two of which represent non-idle, non-sleep performance levels differing from one another; and in response to the received request, determining clock and power characteristics that will achieve the requested operating point and controlling at least one of a clock generator and a power supply of the integrated circuit so as to achieve the requested operating point, where said integrated circuit comprises a plurality of subsystems, and where the received request is automatically generated in response to the software unit, when starting to use a particular subsystem, making a first access to the particular subsystem.
