Abstract
Abstract ： Based on DM642 DSP made by TI Company, integer transform in H. 264 is real- ized. Firstly the theory of the integer transforms in H. 264 is analyzed, and then according to the features of DM642 the H. 264 integer transform code is rewritten using the linear as- sembly language, which effectively reduce the clock cycles to run the module. Experimental results indicate that better performance can be achieved for this work.关键词
