Abstract
In a multimedia system, a method and system for deglitching in a mobile multimedia processor are provided. A deglitching operation may be provided to reduce noise and compensate for strobe signal delays that may result in false bus cycles and other operating errors. A circuit comprising a plurality of delay cells, a multiplexer, and a latch may be utilized to perform the deglitching operation. The delay cells may be selected from several delay options having different time delays based on operating temperature and applied supply voltage. The time delay may be programmable and may be dynamically varied in accordance with the operation of the mobile multimedia processor.
