Coarse-grain reconfigurable architectures - taxonomy -

Digital signal processing for wireless communications is computationally intensive, and hardware support is needed. Coarse-grain reconfigurable arrays provide hardware-like performance with software-like flexibility. There are two major classes of coarse-grain reconfigurable arrays: Multiply-and-ACcumulate and Shift-and-Add. This paper gives an overview of the major devices in these classes under the form of a taxonomy.
