【Abstract】 The VLSI implementation of an MPEG2 video decoder is proposed, in which ASIC structure is used to realize video decoding in MPEG2 standard. Video bitstream, VLD and circuit sequence for the decoder are controlled by an RSIC microcontroller with pipelined Harvard structure. By using the proposed technique, processing speed of the circuit is improved and chip area is reduced.更多还原
