摘要
Processes and apparatuses for characterizing the spatial relationship of two displayed objects. Differences between pairs of coordinates of the two objects are generated. The differences are sequentially stored as binary values in the lower half of a data register and shifted left one bit to preserve the most significant bit of each difference in the upper half of the register. The spatial relationship between the two objects is characterized by accessing a lookup table using a table index, where the table index is the shifted bits in the register's upper half (i.e., a value corresponding to the MSBs of the coordinate differences).
