Trigonometric functions are slow and need a lot of resources to run on embedded systems. How can we calculate these functions in a more efficient way of resources and faster? In this paper we present the implementation on FPGA of the CORDIC algorithm to calculate the sine, cosine, arctangent and vector magnitude. The CORDIC IP (Intellectual Property) is described generically in Vhdl and Handel-C....
The main objective of our paper is to implement on FPGA (Field Programmable Gate Array) an architecture of a method used to detect circles from edge images based on Hough transform algorithm. At first, an algorithm has been developed and tested using Matlab software. The modified algorithm that we have followed to realize our architecture simplifies trigonometric calculations to just simple additions...
Knowing that, the computing process of the S.Mallat Transform algorithm is characterized by a purely sequential structure, and from the fact, the on line mode arithmetic is more suitable for the computation of this kind of operations. We propose in this paper, a new wavelet Transform algorithm and a suitable architecture implemented on a Xilinx FPGA circuit. In this study, we will show how on line...
