Averaged Green function method for numerical computation of diffusion equation and the DSP architecture

Presents an iterative computation scheme for the numerical solution of a diffusion equation, and shows pipeline hardware architecture suitable for the scheme, using digital signal processors (DSPs). The scheme is explicit, and is based on an analytical solution and a Green function, which are obtained from the diffusion equation over a uniform flow (or velocity) field in a three-dimensional boundless region under arbitrary initial condition.
