Abstract

In this paper, an area efficient reconfigurable inverse transformation architecture for multiple standards is proposed. We present a top-down design methodology with complexity analysis, commonalities extraction, and dataflow modeling to systematically design reconfigurable architecture. By exporting and sharing the commonalities, the adder usage of the proposed reconfigurable inverse transform processing element can be reduced 44% compared with the total amount of adders in performing target inverse transform types. Then, the reconfigurable architecture is synthesized using TSMC 0.18 um library. The working frequency is 108Mhz, which is derived from the dataflow scheduling. The area synthesis result is 32k gates, which indicates that the proposed design has more efficient area than other documented design in VLSI implementation. In addition, the proposed architecture also satisfies the accuracy requirement. Therefore, the proposed design have lower cost and enough flexibility for multi-standard purposes with 19201088 resolution and 64 frames per second and the color format is 420 for real time processing.
