Abstract:
1. A method for filtering a frame, the method comprises: determining whether to perform loop deblocking filtering or post deblocking filtering; configuring a hardware filter to operate as a loop deblocking filter or a post deblocking filter according to the determination; determining, by a mode decision unit of the hardware filter, which filter to be applied by a filter arithmetic unit of the hardware filter; processing, by a processing unit executing instructions, at least one portion of a frame to provide at least one processed frame portion, performing, by a hardware filter of an image processing unit that is coupled to the processing unit, deblocking filtering of the at least one processed frame portion to provide at least one filtered frame portion; wherein the processing unit operates independently of the image processing unit; wherein the at least one filtered frame portion is utilized in response to the determination; wherein the deblocking filtering utilizes the filter arithmetic unit; wherein if determining to perform loop deblocking then processing, by the processing unit, a frame portion while loop deblocking filtering another frame portion of the same frame; and displaying processed frames.
