One of the most common approaches to avoid complexity while numerically solving stiff ordinary differential equations (ODEs) is approximating them by ignoring the nonlinear terms. While facing stiff partial differential equations (PDEs) the same is done by avoiding/suppressing the nonlinear …

In this thesis a soft processor programming model and architecture is proposed that is inspired by graphics processing units (GPUs) and well-matched to the strengths of FPGAs, namely highly-parallel and pipelinable computation. The proposed soft processor architecture exploits multithreading, vector …
