Abstract
The present invention relates to an apparatus and method for video coding system. More particularly, it presents a new addressing method that uses the bit allocation approach to simplify the computational circuit. Besides, this method significantly improves anew memory access speed. For the bit allocation requirement, anew memory structure is designed using pseudo address decoding concept to reduce the I/O complexity and to shorten the access time. The memory IP integrated to practical video coding systems is also presented. For the fast motion search, a novel comparison-cell that can do the comparison of n-data at a time based on dynamic logic methodology. The results of n-data are then passed to the m-bit NAND gate for the final comparison, where m corresponds to the word length of each data. Compared to the conventional comparators, the number of transistors can be efficiently reduced and the circuit delay time is also shortened.
