Three-axis accelerometers have been widely used not only in motion sensing but also in tilting sensing nowadays. The tilting angle conversions from 3D acceleration data involves with complicated mathematic calculations such as multiplication, division, square-root and trigonometric functions. Indeed, the conversion can be done by only using simple addition, subtraction, and shifting operations through...
We present a novel computing model that allows to conveniently construct multi-core systems with different computer architectures, ranging from homogeneous many-core architectures to networks of heterogeneous general purpose processor cores or signal processing engines. A hardware library implemented on Field Programmable Gate Arrays (FPGAs) and a compiler provide a platform for prototyping and constructing...
Reconfigurable computers have started to appear in the HPC landscape, albeit at a slow pace. Adoption is still being hindered by the design methodologies and slow implementation cycles. Recently, methodologies based on High Level Synthesis (HLS) have begun to flourish and the reconfigurable supercomputing community is slowly adopting these techniques. In this paper we took a geophysics application...
The eikonal partial differential equation is solved using a modified level set algorithm which is then transformed into a proposed field programmable gate array implementation. The numerical method for isotropic material eikonal hardware engines is extended to angle dependent anisotropic media in two dimensions. This new method transforms the eigenvalue iteration into a process which executes in constant...
