Abstract
An arithmetic logic stage in a graphics processor unit includes arithmetic logic units (ALUs) and global registers. The registers contain global values for a group of pixels. Global values may be read from any of the registers, regardless of which of the pixels is being operated on by the ALUs. However, when writing results of the ALU operations, only some of the global registers are candidates to be written to, depending on the pixel number. Accordingly, overwriting of data is prevented.
