A Two Level Architecture for High Throughput DCT-Processor and Implementing on FPGA

Frequency analysis using discrete cosine transform is being used in a large variety of algorithms such as image processing algorithms. This paper proposes a new high throughput architecture for the DCT processor. This system has got a 2level architecture which uses parallelism and pipelining and has been synthesized on Xilinx Virtex5 FPGA. Synthesis results show that this system works at 150 MHz. Applying DCT on each 8×8 matrix of image take 67 clock pulses. In other words, applying DCT on each pixel takes approximately one clock pulse.
