Abstract
A video decoder has a first processing circuit and a second processing circuit. A shared storage device is accessible to the first processing circuit and the second processing circuit. The first processing circuit performs a first decoding operation according to data access of the shared storage device. The second processing circuit performs a second decoding operation according to data access of the shared storage device. The first decoding operation is at least a portion of a first decoding function complying with a first video coding standard, and the second decoding operation is at least a portion of a second decoding function complying with a second video coding standard different from the first video coding standard.
