Fault-tolerant modular convolvers

A preceding research, concerning the architecture of a convolver capable of accepting a sequence of groups of p samples presented simultaneously and of generating at p output ports the corresponding sequence of convolution groups, is expanded with a new approach. In this architecture the convolver is decomposed into a linear array of p identical “phase-convolvers” associated with identical input networks, each producing one convolution every p. The resulting architecture has high fault tolerant features at different structural levels (the phase-convolvers, the sub-convolvers composing them, the multiplier-adders). Different strategies and alternatives are discussed to introduce different degrees of fault tolerance, suitable for different production and operational environments
