| Abstract: | This paper presents a 2- D DCT algorithm arid its optimized VLSI design, which can be realized by dividing 2-D DCT into two 1-D DCT, and needs only one 1 -D DCT processor. Then by simplifying the coefficients matrix of 2-D DCT and taking the pipelining technology, it uses four multipliers and makes the circuit work with high speed. Such circuit structure has the advantages of modularization, simple wiring and small chip size. Experiments show that the VLSI design is effective. |
