A Reconfigurable Systolic Array (RSA) architecture that supports the realization of DSP functions for multi-carrier wireless and multi-rate applications is presented. The RSA consists of coarse-grained processing elements that can be configured as complex DSP functions that are the basic building blocks of Polyphase-FIR filters, phase shifters, DFTs, and Polyphase-DFT circuits. The homogeneous characteristic of the RSA architecture, where each reconfigurable Processing Element (PE) cell is connected to its nearest neighbors via configurable SWitch (SW) elements, enables array expansion for parallel processing and facilitates time sharing computation of high-throughput data by individual PEs.
