Claim 15:
16. An electronic device for sharing frame decompression circuitry, the electronic device comprising:
at least one integrated circuit configured to:
decode, by a video decoder, a video stream to produce multiple decoded frames, the video decoder including a frame decompressor and a frame decompressor controller;
accept, from the video decoder at the frame decompressor controller, a first request for a first decompressed frame;
decompress, by the frame decompressor, a first compressed frame to produce the first decompressed frame, the first compressed frame produced from the multiple decoded frames;
provide, to the video decoder, the first decompressed frame responsive to the first request;
accept, from a display controller at the frame decompressor controller, a second request for a second decompressed frame;
decompress, by the frame decompressor, a second compressed frame to produce the second decompressed frame, the second compressed frame produced from the multiple decoded frames;
provide, to the display controller, the second decompressed frame responsive to the second request;
store, by the frame decompressor, at least a portion of the second decompressed frame in a video buffer; and
write, by the frame decompressor controller, into a synchronization register at least one value indicative of a stored status of the portion of the second decompressed frame.
