| 摘 要： | Aim To present an ASIC design of DA-based 2-D IDCT. Methods
In the design of 1-D IDCT is utilized a Chen-based fast IDCT algorithm, and multiplier
accumulators based on distributed algorithm contributes in reducing the hardware amount
and in enhancing the speed performance. Results and Conclusion VHDL
simulation, synthesis and layout design of system are implemented. This 2-D IDCT ASIC
design owns best timing performance when compared with other better designs
internationally. Results of design prove to be excellent.
