Claim 18:
19. An electronic device comprising:
a frame decompressor configured to decompress multiple compressed frames to produce multiple decompressed frames;
a frame decompressor controller coupled to the frame decompressor and configured to arbitrate access to the frame decompressor for multiple cores, the frame decompressor controller comprising a time-sharing protocol handler configured to establish a time-sharing protocol to share the frame decompressor between the multiple cores, the time-sharing protocol handler configured to at least one of:
establish the time-sharing protocol to include multiple timeslots that are assigned to at least one core of the multiple cores; or
establish the time-sharing protocol to permit reception of an interrupt signal from a core of the multiple cores, the interrupt signal indicative of a request for at least one decompressed frame;

a first core of the multiple cores coupled to the frame decompressor controller, the first core configured to obtain via the frame decompressor controller a decompressed frame of the multiple decompressed frames produced by the frame decompressor; and
a second core of the multiple cores coupled to the frame decompressor controller, the second core configured to obtain via the frame decompressor controller another decompressed frame of the multiple decompressed frames produced by the frame decompressor,
the first core and the second core configured to perform video transcoding.
