Title:
FREQUENCY CHANGE TECHNIQUE FOR ADJUSTING OPERATING FREQUENCY TO COMPENSATE FOR AGING ELECTRONIC COMPONENT
Document Type and Number:
Japanese Patent JP3965169
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a frequency change technique that adjusts an operating frequency of an electronic system to compensate for one or more aging electronic components.
SOLUTION: A number of performance parameters for an electronic system are determined at a particular age of the electronic system. The performance parameters can be correlated to a maximum operating frequency of electronic components of the electronic system for the particular age of the electronic system. The operating frequency of the electronic components is adjusted in accordance with the performance parameters. The performance parameters can include prior operating frequencies, hours of operation, ambient temperature, and supply voltage.
