Claim One:
1. A signal processing circuit comprising: an input for receiving an input pattern-data array having values and data order significance; a series of processor blocks processing a pattern-data array to provide improved human perception of the pattern-data array; a feature detector receiving a pattern-data array to identify a predetermined feature in the pattern-data array; and a power management circuit receiving a mode command and operating: 1) in a first mode to activate a first set of the processor blocks to process the input pattern-data array to provide a first processed pattern-data array for output on a human machine interface, the first processed pattern-data array offering improved human perception quality on the human machine interface over the input pattern-data array, and (2) in a second mode to activate a second set of the processor blocks different from the first set to process the input pattern-data array to provide a second processed pattern-data array for processing by the feature detector, the second processed pattern-data array offering reduced human perception quality on the human machine interface compared to the first processed pattern-data array, the second set of processor blocks consuming less power than the first set of processor blocks.
