Abstract:
A single chip digital signal processing device for real time video/audio compression, said device comprising:a plurality of processors, wherein said plurality of processors comprise: a video input processor which receives, analyzes, scales and processes a digital signal, a motion estimation processor which receives said processed signal, produces a motion analysis therefrom; a digital signal processor which receives said processed signal, and according to said motion analysis, compresses said processed signal and produces a compressed processed signal, a bitstream processor which receives and formats said compressed processed signal; and a multiplexing processor which multiplexes plurality of digital signals and produces a multiplexed stream; wherein said motion estimation processor operates on a macroblock a of frame I, said digital signal processor operates on macroblock of frame K, said bitstream processor operates on macroblock c of frame I, said multiplexing processor operates on frame J, wherein a&gE;b&gE;c, and I&gE;J; and wherein processing and transfer of said signals within said device is done in a macroblock-by-macroblock processing.
