A Pipeline Architecture for Processing of DNA Microarrays Images

In this paper we present a pipeline architecture specifically designed for processing of DNA microarray images. Many of the pixilated image generation methods produce one row of the image at a time. This property is fully exploited by a pipeline which takes in one row of the produced image at each clock pulse and performs the necessary image processing steps on it. This will remove the present need for sluggish software routines that are considered a major bottleneck in the microarray technology. The size of the proposed structure is a function of the width of the image and not its length. The proposed architecture is proved to be highly modular, scalable and suited for a Standard Cell VLSI implementation.
