Magnetic field calculations are by far the most computationally demanding part of a micromagnetic simulation — there are significant efforts to use hardware accelerators (such as GPUs) to speed up calculations. Dedicated hardware, such as FPGAs could offer even higher performance, and flexibility / reprogrammability is usually not a requirement at this level of the computation. In this paper we present...
In this paper, we demonstrate an optically inspired massively parallel non-Boolean operator which can emulate 3D wave dynamics on a 2D FPGA-based architecture. The algorithm is based on the Paraxial Helmholtz Equation: which describes the beam propagation through different media with different refractive indices. To solve this wave propagation equation numerically the FPGA-accelerated hardware have...
In this paper, we demonstrate the FPGA implementation of a massively parallel, non-Boolean pattern-matching algorithm. The algorithm is based on the concepts of optical computing: quasi-optical wave equations are solved numerically, using FPGA-accelerated hardware. The FPGA-based wave-equation solver is very well parallelizable, so the resulting pattern-matching algorithm will also be amenable to...
A visual sense-and-avoid system is introduced in this paper. The system is designed to operate on small and medium sized UAVs, and to be able to detect and avoid small manned and unmanned aircrafts. The intruder detection is done on a 4650×1280 sized video flow which is processed by a many-core cellular processor array real-time.
There are a large number of problems which can be accelerated by using architectures on Field Programmable Gate Arrays (FPGA). However sometimes the complexity of a problem does not allow to map it onto a specific FPGA. In that case analysis of precision of the arithmetic unit which may solve the computational problem can be a good attempt to fit the architecture and to accelerate its computation...
Embedded sensor-processor system is being developed for on-board UAV (Unmanned Aerial Vehicle) safety applications. The role of the device is to detect intruder airplanes which are on or close to collision course. Due to weight, power, size, and cost requirements, the visual approach leads to feasible solution only. In our design, 5 cameras are applied to collect visual data from a large field of...
An on-board UAV high-performance collision avoidance system sets up drastic constraints, which can be fulfilled by using carefully optimized many-core computational architectures. We report here a case study, where we implemented a many-core processor system, which can process a 100 megapixels/sec video flow, identifying remote airplanes, tracking flying objects by implementing computationally intensive...
