Design of two dimensional inverse DCT module based on FPGA
Abstract:This paper describes implementation of two-dimensional inverse discrete cosine transform ( IDCT ) module on FPGA which assists DSP to decode MPEG-4. The architecture which is realized with multipliers and adders based on embedded Block RAMs is parallel, which has been contributed to reduce hardware requirement and to achieve high-speed operation.
