Parallel Extraction Architecture for Numerous Particles
We propose new processor architecture for real-time particle measurement. This architecture is able to extract particle information at the microsecond level, even when an image has several thousands of particles. The particle information includes various features such as the size, centroid, orientation, rough shape information, and so on. This kind of processing enables to construct a system which could realize high performance on fluid analysis as well as product inspection. The covering fields are medical science, chemistry and industry application.
Fig.1 Parallel Extraction
The proposed architecture simultaneously extracts the moments of multiple particles in parallel by utilizing the massively parallel architecture. The basic concept of this parallel extraction is shown above. This enables a significant reduction in the amount of calculation required. In addition, asynchronous operation between processing elements allows fast processing.
