ABSTRACT:
A Fine-Grained Microstructure Processor (FMP) (10) for solving assignment and correlation problems that utilizes a pair of arrays (22, 24) of cells (26) to represent the position of two set of two-dimensional data points (14). The arrays (22, 24) are divided by a predefined shaped (16) having a plurality of regions (18). The FMP (10) counts the number of data points (14) in each region (18) and then finds the difference between the resulting sums from corresponding regions (18) in the two arrays (22, 24). The differences for each regions (18) are added together by an accumulator (34) to determine a correlation factor. The data in the second array (24) is then shifted until a different data point (14) occupies a particular position with respect to the predefined shape (16) and a new correlation factor is found. The FMP (10) finds a correlation factor for each data point (14) in the second array (24) and the lowest correlation factor represents the best match between a data point (14) in the first array (22) at a particular position with respect to the predefined shape (16), and the point in the second array (24) yielding the best match. The FMP (10) may then shift the data in the first array (22) and repeat the above process to match each data point (14) in the first array (22) with a data point (14) in the second array (24).
