In this paper, we report on design and fabrication of the pipelined digital correlator (PDC) for the opto-electronic discrete correlation processor (OEDCP). The OEDCP consists of optical fan-in and fan-out interconnection systems and several number of PDC's with optical I/O ports. The OEDCP achieves high processing performance with sophisticated combination of optics and electronics. We design and fabricate a prototype of the PDC which is the processing engine of the OEDCP. For the prototype, the pixel number of the input and the output images is 88 and that of the kernel is 33. The designed chip is composed of approximately 10,000 transistors. Operation of the fabricated chip was verified using test vectors.
