3D-WASP devices for on-line signal and data processing

While hybrid and monolithic-WSI technologies have brought about dramatic improvements in the density of integration of embedded massively parallel computers (MPCs), systems and applications engineers continue to demand even more processing power in less space. The emerging technology of 3D-WSI offers a way of meeting this challenge, giving the potential for step-function increases in parallelism using existing WSI package options. It also permits independent scaling of I/O, parallel processing power and control, leading to a degree of cost-effectiveness that 2D-WSI cannot match. The paper explores the potential of 3D-WASP and reports the results of a study into the engineering feasibility of such a device.< >
