WebJan 18, 2024 · We propose a reconfigurable control-bit generation algorithm for rotation and sub-word rotation operations. The algorithm uses a self-routing characteristic to configure an inverse butterfly network. In addition to being highly parallelized and inexpensive, the algorithm integrates the rotation-shift, bi-directional rotation-shift, and sub-word rotation … WebAug 15, 2024 · Many techniques like encryption, steganography, watermarking are used for sending multimedia information securely over the internet. This paper focuses on encryption technique for secure transmission of images. For this, a Secure Dynamic Decision based Permutation and Butterfly Network Topology (BNT) based Diffusion (SD2PBD) model …
Webnetwork. A Benes network consists of a butterfly network followed by an inverse butterfly network. An n-bit butterfly network consists of log@) stages. In each stage, n bits are divided into n/2 pairs. Two bits in a pair can go to the same position at the output or exchange position with the other one. This is determined by a single control bit.
WebIn this paper, a new class of permutation instructions based on the butterfly interconnection network is proposed to address the general subword rearrangement problem. It can be used to perform arbitrary permutation (without repetition) of n subwords within log n cycles regardless of the subword size. The instruction coding and the low …
WebButterfly Network, Benes Network[1] I. PRELIMINARIES Definition1.2: A graph is an ordered pair G = (V, E) comprising set V of vertices or nodes together with a set E of edges or lines, which are 2-element subsets of V[3]. Definition 1.3 An edge partition of a graph G is a partition of its edges E into subsets {E j}. We can define {V j} to be ... christmas events burlington county njWebIn this paper the construction of a switching network capable of n !-permutation of its n input terminals to its n output terminals is described.
