Least-time path fast marching method for seismic travel time computing: theory and implementation

摘要: The main contribution of this thesis is the development Least-Time Path Fast Marching Method and design algorithm implementation frame on a digital hardware platform. This work imports application specific circuit technology into domain computational geophysics problem solving. -- In thesis, firstly, knowledge reviewed theoretical fundamental introduced. From theory that computes seismic travel time developed. section, issues parallel 3D extension are discussed. Software simulations arc run for verifying algorithm, while programming solution multiprocessor platform introduced as well. At end. proposed prototyping system built Xilinx FPGA. not only an report project, but also includes consideration discussion future direction reconfigurable computing applications methodology.
