Full-Custom PCB Implementation of the FDTD/FIT Dedicated Computer

As one of the possibilities of high-performance computing technologies for electromagnetic-field computation, the authors have been working in the design and development of a dedicated computer of the finite-difference time-domain (FDTD) method or the finite integration technique (FIT) for microwave simulations. So far, to minimize memory-access overhead, a parallel memory-access architecture was proposed, and the validity of the machine operation was confirmed by VHDL logic simulation. However, to implement the FDTD/FIT dedicated computer on any real hardware, it is essential to consider concrete hardware construction in detail. This paper presents implementation of the FDTD/FIT dedicated computer on a custom printed-circuit board.
