A VLSI implementation of the H.324 audiovisual codec is described. A number of sophisticated low-power architectures have been devised dedicatedly for the mobile use. A set of specific functional units, each corresponding to a process of H.263 video codec, is employed to lighten different performance bottlenecks. A compact DSP core composed of two MAC units is used for both ACELP and MP-MLQ coding schemes of the G.723.1 speech codec. The proposed audiovisual codec core has been implemented by using 0.35 μm CMOS 4LM technology, which contains totally 420 K transistors with the dissipation of 224.32 mW from single 3.3 V supply |
