In Digital Image Processing, the discrete linear convolution is used as a basis for linear filtering. In this paper, the multiplier operation involved in discrete linear convolution operation using CORDIC and Vedic algorithm is implemented on FPGA Spartan XC3S1000 device. Performance evaluation of these two approaches is done and the trade off in terms of Area, Power and Speed is tabulated. It is...
Coordinate Rotation Digital Computer (CORDIC) based digital signal processing has become an important tool in communications, biomedical and industrial products, providing designers with significant impetus for making algorithm into architecture. In this paper, a new kind of CORDIC algorithm was presented which was based on the state machine structure and iterative operation of multilevel pipeline...
Existing JPEG2000 2D-DWT architectures all fail to achieve a higher system throughput because they do not exploit the parallelisms fully. In this paper, a high throughput 2D-DWT encoding system is proposed firstly. It exploits three parallelisms of the 2D-DWT algorithm to achieve 1.7 times system throughput over the fastest existing design. For a one-level N times N 2D-DWT, it takes only N2/4 + N...
