Stacking technology is an approach by which VLSI dies are stacked to form a three-dimensional logic unit. The free space optical interconnect is a technology suited for dealing with the unique constraints of three-dimensional stacked processors. The architecture supports the calculation of two dimensional fast Fourier transforms (FFT) and other signal processing functions using free space optical interconnects for communication between planes and stacks. Major architectural points are the development of reliable high-speed serial bus and an inter-processor communication protocol. This protocol must account for the unique requirements of the free space optical interconnects while maximizing the bandwidth available.
