Embodiment Construction

[0077] The present invention proposes two new hardware instructions, preferably directly accessible by application-level software (SW), as opposed to being accessed by BIOS / operating system (OS) and device drivers.

[0078] User-mode instructions are instructions that an application process can execute directly without the assistance of the operating system. Usually hardware-related instructions can only be executed in a "supervised state" or some similar mode reserved for the operating system. Therefore, for an application program to start a hardware operation, it usually must go through the following process:

[0079] - transition from user mode to OS mode,

[0080] - the OS executes hardware instructions, and

[0081] - Transition back to user mode (this may involve scheduling decisions, and possibly scheduling of another process)

[0082] A first instruction according to the invention may be Speed_Up(x%), this instruction preferably requests the hardware to speed up by ...

Abstract

The invention discloses an instruction, processor, system and method which allow application level software to explicitly request a temporary performance boost, from computing hardware. More specifically it relates to advanced management of working frequency of a processor in order to achieve the performance boost. Preferably a processor according to the invention may be implemented in electronic exchanges or similar applications where peak periods may occur.

Description

technical field [0001] The present invention relates generally to managing processor operating frequency in computer systems and electronic devices. Background technique [0002] Many different kinds of computer systems exist today. The systems can range from a single computer to a distributed computer system interconnected by one or more networks. [0003] A very important problem with the systems and computers described above is that they will be subject to peak cycles at one point or another, which they can be very difficult to handle. Typically the system is designed to handle peak periods up to a certain level. This rating is usually based on forecasting future traffic scenarios in the system weighted against hardware cost. Thus, when attempting to estimate the capabilities of the system, there is a risk in the system of underestimating future communication traffic, which may cause the system to crash. An example of an accident in which the system capacity was insuf...
