Many digital signal processor designers and manufacturers are facing one big challenge, that is, how to perform complex mathematical function calculations more efficiently. To gain efficiency, it is needed to dig inside our complete designing cycle which contains algorithms, architectures, hardware technology, power supply etc. Fast Fourier Transform (FFT) is widely used transform in digital applications...
The paper describes the design of 2D-discrete cosine transform (DCT) which is widely used in image and video compression algorithms. The objective of this paper is to design a fully parallel distributed arithmetic (DA) architecture for 2D-dimensional DCT to be implemented on field programmable gate array (FPGA). DCT requires large amount of mathematical computations including multiplications and accumulations...
