Abstract: This invention provides a clock control circuit, which can be added to any pipeline-processor to solve timing problems arising from variations due to process outcome and environmental conditions. Critical instructions are detected (instructions that exercise critical paths) in conjunction with environmental sensing (such as process, temperature and voltage). This information is used to control cycle stealing.
