Abstract
A way of dynamically modifying error recovery on a communications controller to operate at the lowest power mode allowed by current error rate conditions. When operating conditions are good and a small number of errors are detected, a low power error detection/correction mode is entered saving battery life. The low power error correction mechanism runs at a slower frequency and lower power than the high power mechanism and maintains the same data rate for the controller, thus saving power. Selecting the controller error (power) mode may be externally, such as by a person using a control dial on a cellular telephone when the voice data gets too noisy. Alternatively, the selection can be automatic, a critical error level detector internally making the selection.
