We have developed a media processor core for MPEG4/H.26X codec LSI, which realizes a real-time bi-directional encoding/decoding for CIF-resolution video at the frame rate of 30 fr/s. The core processor contains 6.3 M-transistors on only 14 mm silicon area and consumes 280 mW at 1.8 V. It features an MPEG-oriented hybrid architecture which incorporates a SIMD processor optimized for matrix-operation, a programmable VLC engine and two-dimensional multifunction DMA. Another features are a memory reduction approach by hardware assist and an operand isolation scheme, which realizes low cost and low power characteristics, respectively
