An Overview of Reconfigurable Hardware for Efficient Implementation of DSP Algorithms

Abstract

-Reconfigurable hardware is emerging as the best option for the efficient implementation of complex and computationally expensive signal processing algorithms. Reconfigurable hardware exploits the benefit of high of computational efficiency of hardware as well as flexibility of software implementation. Field Programmable Gate Array (FPGA) which finds wide range of applications in the field of signal processing, wireless communication, image and video processing has gained popularity as a reconfigurable logic over past decade. In this paper, various hardware aspects of reconfigurable such as architectures and models including external coupling and run-time reconfigurable systems have been studied. Moreover, a case study of most widely used commercial FPGA technologies from Xilinx and upcoming three dimensional 3D-FPGA architecture is presented. It is revealed that the reconfigurable hardware can be used in a variety of DSP applications. FPGA implementation of digital signal processing applications show enhanced outcome in terms of speed as compared to software implementation and previously reported architecture.

“…The clock is the configuration clock bit and the configuration data is slide after all rising edge of this clock to start the simulation through a switch. Here, the FPGA offers a direct on-board interface which is FPGA Mezzanine Card (FMC) daughter card connector as well as many high level system capabilities, which is a dual channel 16 bits to convert digital-to-analog signal with maximum voltage of 2.5 V [21][22][23]. The action potential waveform in real-time data from the system will be acquired using a data logger and displayed on the LCD in which the data acquisition system must remain tethered to a computer to acquire data.…”

“…The main advantage to digital signal processing within an FPGA is the ability to adapt the implementation to match system requirements [2,3]. This means in a multiple-channel or high-speed system, you can take advantage of the parallelism within the device to maximize performance.…”
