Abstract
To determine whether a first n-bit binary data value and a second n-bit binary data value in a data processing system, such as texel position coordinates in a graphics processing system, are the same or differ from each other by exactly one, it is determined whether the first and second data values excluding the least significant bits of the data values are the same as each other, and the least significant bits of the data values are compared. A mask value that is generated for each data value using an XOR operation and a thermometer scanning operation is used to generate an output value for the two data values, based on whether the mask values for a bit position for the first and second data values are both set or not, and a comparison of the bit values of the first and second data values for that bit position.
