Sound Source Localization Application on Nios II Embedded System
Abstract: This paper presents the software implementation of binaural sound source localization employing interaural time difference (ITD) method on NIOS system built on FPGA Altera DE2-70. Hardware components on NIOS system were configured and generated using SOPC builder. FFT based cross correlation algorithm was developed for ITD computation. The developed system was tested in a semi-anechoic room and used white noise as sound source. Best sound arrival estimation obtained for sound …

FPGA Implementation of SoC Design using Softcore Processor and Custom Peripherals, Custom Instruction for Robotics and Automation
Abstract: The general definition of SoC is the on-chip integration of a variety of functional h/w blocks to suite a specific product application. In traditional technology designed using on board integration of functional blocks for any application, this leads to less performance. Nowadays productivity gap will be reduce by making compact, life of device and Time to market. So using FPGA demonstrating building of SoC using custom peripherals. FPGA (Field Programmable …

Design and Development of a Multifunction FPGA-based Data Acquisition System using Nonlinear Duty-cycle Modulation Technique
Abstract: AbstractA new generation of DAQ based on duty-cycle modulation technique is presented. It describes the design and prototyping of a FPGA-based data acquisition and signal generation board using the duty-cycle modulation technique and with computer-based software interface. The system is built around the DE0-Nano development board that embeds an Altera cyclone IV FPGA in which a NIOS II processor running at 100 MHz has been instantiated. The conversion technique from …
