Spatial computing using Null Convention Logic

We present the design and organization of an homogeneous asynchronous bit-level array based on Null Convention Logic. A bit element (bel) array represents a bit-level hybrid processor that exhibits both Spatial and Temporal computing characteristics. The bit elements are organized in a 2D grid, with eight-way connectivity. Programs represented as Directed Acyclic Graphs can be mapped to the array either fully statically or with a small level of element reuse (dynamic mapping).
