Abstract
An example embodiment of a method and apparatus for dynamically changing computer system configuration to improve software application performance includes a system logic device that implements at least two different configurations. The system logic device may change configuration depending on what software application is running. The system logic device can change configurations while the computer system is running and may change configurations in order to optimize performance for whatever application is currently running.
Claims4
A system, comprising:
- a microprocessor;
- a non-volatile memory device to store a plurality of configuration information entries;
- and
- a system logic device coupled to the microprocessor, the system logic device including
- a configuration register to store a value read from one of the plurality of configuration information entries stored in a selection table located in the non-volatile memory device, and
- an arbiter including a plurality of arbitration policies, the arbiter to use one of the arbitration policies according to the value stored in the configuration register, the arbiter to dynamically change arbitration policies in response to a change in the value stored in the configuration register.
