A VLSI architecture for a low complexity intraframe subband image coding for HDTV signals is presented. The generalized quadrature mirror filters (GQMFs), which have smaller overall delay, are optimized in order to achieve high coding efficiency. The filter design exploits a symmetry property among different filter coefficients which, in turn, reduces the hardware complexity of the VLSI architecture substantially. The architecture is designed with 1 μm CMOS technology using the scalable design rules of MDS Integrated Services Inc. (MOSIS). The VLSI architecture contains approximately 200,000 transistors and it is capable of operating at a speed of 34 MHz. The HDTV signals are decomposed into seven bands. The baseband is DPCM encoded and the high bands are PCM encoded. It is shown that high quality HDTV images can be obtained at a low bit rate as 0.654 bpp (bits/pixel)
