VLSI Architecture for a Low Complexity Algorithm for Intraframe Sub-Band Coding of HDTV Images
Awad Kh. Al‐Asmari, Rana Ejaz Ahmed · 1994
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 architecture substantially. The architecture is designed with lpm CMOS technology using the scalable design rules of MOS Integrated Services Inc. (MOSIS). The VLSI architecture contains approximately 200,000 transistors and it is capable of operating at a speed of 34 MHz.
