Abstract :
The GAM II pyramid, made up of 172 custom microcircuits designed for the massively parallel processor (MPP), is described. The pyramid structure is broken down into the following sections: the basic processing element organization, the daughter cards that contain the processing elements, the back plane that contains the daughter cards, and the processing element adder network. The GAM II pyramid is a hierarchical structure with a total of 1365 processing elements. The sequencer designed for controlling this structure is capable of executing pyramid oriented primitives similar to an add and subtract operation, as well as independent procedures similar to convolution. The pyramid contains three control buses embedded in the hardware in anticipation of a future control system that will contain three independent control units
