The remainder of the paper can be categorized of following sections which are described as follows. In this paper we prepare a design methodology to develop reconfigurable SDR platform using FPGA.
Nios modelsim software#
The solution of above big problems can be solved by using the software defined radio (SDR), which comprised of both software and hardware, it use a reprogrammable ability of field programmable gate array (FPGA) or any possessor to built an open architecture. Therefore, deploying a new algorithm or an updated standard requires new hardware.

In RV College of Engineering,Bangalore,560059.Email id- Krishnamurthy Vaidyanathan, CEO of EI LABS INDIA PVT LTD.Ĭommunications devices designed with application- specific integrated circuit (ASIC) technology suffer from one very significant limitation-the integrated circuits are not programmable. ,560059.Phone number-9019121052,Email P.Nagaraju ,Associate Professor in Telecommunication Department Barun Sharma currently pursuing Masters of Technology in DigitalĬommunication in RV College of Engineering, Bangalore.They have a short life and are designed to be discarded and replaced. Most radios are hardware defined with little or no software control they are fixed in function for mostly consumer items for broadcast reception. The twentieth century saw the explosion of hardware defined radio (HDR) as a means of communicating all forms of audible visual, and machine-generated information over vast distances. Although older systems combined fixed processors and integrated circuits, current technology allows designers to combine both processors and dedicated logic to implement complete embedded computing systems as Systems-on-Chip (SoC) using either ASIC or FPGA platforms. This has led researchers to investigate numerous issues that arise from Hardware/Software co design. The architecture of the proposed methodology presented in this paper were prototyped using a Cyclone IV Starter Board (DEO Nano), which is based on Nios II Embedded Evaluation Kit.Įmbedded computing systems typically comprise both processors and dedicated logic modules to meet design specifications that include performance, area, power, and cost constraints. As an example to illustrate this methodology reconfigurable coprocessor consisting of wrapper module along with controller module are designed to control external device like LCD. The methodology adopted to develop reconfigurable platform can be implemented for performing mathematical operation such as addition, subtraction and to perform complex operation such as Autocorrelation, it can also be used in Image Processing, Cryptography etc. It ties in to the sequential RISC processor based C programming framework where in the coprocessor performs specific functions, replacing a C function call. The architecture that we have developed for the generic reconfigurable coprocessor is well suited for multiple application domains. Since there is no cost to reprogramming an FPGA, system performance can be measured on-chip in the runtime environment and the system’s architecture can be altered based on an evaluation of the data to meet design requirements.This paper concentrates on designing a reconfigurable platform which consists of reconfigurable coprocessors that can be used in various applications. Using an FPGA as the implementation platform introduces greater flexibility into the design process and allows a new approach to embedded system design. Current technology allows designers to implement complete embedded computing systems on a single FPGA. Ībstract - : The Altera Cyclone family of FPGA provides the ability to perform run time reconfiguration which is known as Dynamic Reconfiguration.
