Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to an integer transformation device used in a video encoder and a realization method thereof. Background technique [0002] As the integrated circuit manufacturing process enters the stage below 45nm, the scissors gap between the development of integrated circuit design and the progress of integrated circuit technology continues to increase. Data flow algorithms, especially digital media ASIC (Application Specific Integrated Circuit, Application Specific Integrated Circuit) design, face problems such as long design cycle, poor flexibility, poor scalability, etc., and it is difficult to meet the needs of rapid product launch and continuous improvement of functions. [0003] In terms of current IC industry needs, design speed has become an important consideration in IC design methodology. When an integrated circuit manufacturer or an integrated system supplier considers the basic i...
