An approach for field programmable gate array (FPGA) based embedded system dynamic current consumption measurement is presented in the paper. The measurement method is based on current conversion to time interval. The time interval is then measured using timer implemented in FPGA. Measurement uncertainty budget analysis is performed. It reveals key components and their parameters mostly affecting...
In this paper we present a highly integrated, Field Programmable Gate Array (FPGA) based induction measurement system for low conductivity object applications. Exploiting under-sampling and demodulation techniques, the system can operate at higher frequencies (>10MHz) than previously reported. Details are discussed in both hardware and software aspects. Simulations and experimental results for...
This paper presents dual sensor based loudness management system for television viewing at home environment in compliance with BS1770 loudness measurement standard. The aim of the research was mainly to address the issue of sudden increase in loudness during commercials in between TV programmes. Same approach works for any TV programme as well. The scope of this research reported here was limited...
A method of converting an unmatched image frame rate converter is presented. This low processing power method solves the problem of an unmatched frame rate between the image source and the instrument display apparatus, especially in a power limited condition. We used a Field Programmable Gate Array (FPGA) device as the design platform because of its flexibility and can be further transferred into...
In this paper, a new digital demodulation method was proposed for capacitance measurement in AC-based electrical capacitance tomography (ECT) systems. The proposed demodulation method can be carried out in the following steps: (1) measure the phase difference between the in-phase reference signal, i.e., the digital form of the excitation signal, and the digitalized measurement signal by using the...
Graphics processor units (GPU) are specialized hardware accelerators that can be utilized for computations needing high parallelism and high memory bandwidth. Propelled by the attractive Flops/$ ratio and its capability to outperform a CPU cluster at the equivalent cost, large-scale GPU clusters are gaining popularity in the high-performance computing (HPC) community. However, the design challenges...
