Coarse-grained reconfigurable array

A coarse-grained reconfigurable array or coarse-grained reconfigurable architecture (CGRA) is a class of spatial computing hardware built from a relatively large number of processing elements (PEs) connected through a programmable, statically or dynamically reconfigurable on-chip interconnect. By reconfiguring both the operation of each PE and the routing between PEs, a CGRA can be specialized to implement the dataflow graph of a computation, most often the body of a performance-critical loop.
