%T A transform accelerator for a transputer system %A C. J. Dodge, P. G. B. Ross, P. E. Undrill, Alastair R. Allen %E Alastair R. Allen %B Proceedings of WoTUG\-15: Transputer Systems \- ongoing Research %X A DSP based image transform accelerator for a transputer system is described. The formal specification language Z has been employed in the accelerator design, examples of which are presented including aspects of the refinement process and some of the problems encountered in working with a combined hardware/software specification.
