Abstract
A pixel processing apparatus receives pixels from an external source (100) and stores them in a storage area (110). A data path (120) performs mathematical operations and tests whether or not a pixel is to be suppressed. For an effective memory access, a control logic (130) provides addresses to the storage area (110). The control logic (130) receives status data from the data path (120), indicating whether or not a pixel is to be suppressed and modifies the status register (140) accordingly. The control logic (130) prevents the data path (120) from performing further operations on a pixel if the status register (140) indicates that the pixel is to be suppressed. Preferably, the control logic suppresses address generation for the location of the pixel in question if said status register (140) indicates that the pixel is to be suppressed.
