This paper presents area-efficient building blocks for computing fast Fourier transform (FFT): multiplierless processing elements to be used for computing of radix-3 and radix-5 butterflies and reconfigurable processing element supporting mixed radix-2/3/4/5 FFT algorithms. The proposed processing elements are based on Wingorad Fourier transform algorithm. However, multiplication is performed by constant...
This paper presents a novel runtime-reconfigurable, mixed radix core for computation 2-, 3-, 4— point fast Fourier transforms (FFT). The proposed architecture is based on radix-3 Wingorad Fourier transform, however multiplication is performed by constant multiplication instead of general multiplier. The complexity is equal to multiplierless 3-point FFT in terms of adders/subtractors with the exception...
Advanced Encryption Standard (AES) algorithm incorporates a byte permutation operation which reorders the bytes within a 128-bit data block. This permutation can be described by reading the input data bytes into a 4×4 matrix called state in column wise and shifting the rows by one, two, or three bytes to the left. In decryption, the shifting is reversed, i.e., the rows are shifted to the right. While...
