Due to its programmability and low-cost characteristics, one of the most used digital devices to synthesize chaotic systems is the field-programmable gate array (FPGA), which is recommended for fast prototyping. In this manner, this paper shows the experimental observation of seven chaotic attractors that are simulated using the Verilog hardware description language, and implemented in an FPGA. The seven designs are Lorenz-type systems, which are designed from the discretization of their equations using the well-known Forward Euler method. The block description of the seven chaotic systems employs the fixed-point numerical format using 32 bit. The simulations of the chaotic systems using Matlab and Active-HDL software, along with the block diagrams of the designs, are presented. The final part of the work illustrates the experimental attractors on a Teledyne Lecroy oscilloscope, obtained by using an FPGA Cyclone II EP2C35F672C6 and a 16-bit digital-to-analog converter.KEYWORDS: Chaotic oscillatorChaosOne-step methodFPGAFixed-point format AcknowledgementsJ.D.

The efficient design of multipliers to meet various design requirements is still an active area of research. In this paper, a thermo-inspired metaheuristic called population-based simulated annealing algorithm, for the design of multipliers using four different resource types, is proposed. Metaheuristics suffers from the problem of scalability and non-convergence as the size and complexity of the circuit increase. Four types of partitioning approaches- output, input, input-output and hybrid-output partitioning are proposed to overcome the same. Proposed partitioning approaches have increased the success rate and reduced the time to realize the circuit. The multipliers designed are synthesized on Cadence Genus with 90 nm technology and compared with traditional designs such as Array, Wallace tree, Dadda and Booth multipliers to conclude that metaheuristics are capable of generating near-optimal solutions in terms of power, area and delay.","PeriodicalId":470300,"journal":{"name":"IETE Journal of Education","volume":"485 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135791838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
