We introduce systolic arrays for the real time solution of some general convolution problems. This paper is devoted to illustrate the power of the divide-and-conquer approach (which is well-known for sequential algorithms) for the design of efficient systolic architectures. We give three applications to words problems: the computation of the occurrences of a give word in a string; the real-time palindrome recognizer; the real-time square acceptor. This divide-and-conquer technique can be viewed as the last step of the methodology introduced by {\it C. E. Leiserson} and {\it J. B. Saxe} [J. VLSI Comput. Syst. 1, 41-67 (1983; Zbl 0532.94015)] for the design of systolic systems.
