Optimizations of Scatter Network for Sparse CNN Accelerators
Sparse CNN (SCNN) accelerators tend to suffer from the bus contention of its scatter network. This paper considers the optimizations of the scatter network. Several network topologies and arbitration algorithms are evaluated in terms of performance and area.
