Two-dimensional digital filtering using constant-I/O systolic arrays

We present in this paper systolic arrays with constant number of input/output (I/O) ports for twodimensional (2-D) FIR and IIR filtering. Our design has an array of L × N processing elements (PE’s), where L (≤ N) is a technology-dependent parameter related to the number of I/O ports. Each PE in our design has a microprogrammed arithmetic logic unit (ALU), a control unit, a fixed number of I/O buffers, and O (N /L) memory. Our design specializes to a square mesh when
