Abstract
Modern mobile devices are sufficiently powerful to execute computationally intensive mathematical problems. This study presents an implementation of a two-dimensional transmission line matrix method (TLM) solver executing on a Smartphone. Software development and architectural design are discussed, focusing on object-oriented strategies for modular and reusable code. Optimisation strategies are also discussed, with large variations in performance observed dependent on the data-caching method that is used. Swapping between data buffers using pointers was shown to be the most effective method, offering significant performance gains over the original software. It was shown for a mesh measuring 246 by 370 nodes running on an iPhone 4 that an update rate of 9.37 fps could be achieved.
