摘要： A display controller device for processing image data has a data processor for generating a display signal. The device has a writeback unit having an input coupled to the display signal and an output coupled to a debug interface. The writeback unit has a slice controller for defining a set of slices of the image and consecutively selecting slices of the set, and a slice selector for sampling pixel data from a selected slice. A slice buffer is coupled between the slice selector and the debug output for temporarily storing the selected pixel data. The slice controller transfers the selected pixel data to the debugger and subsequently selects a next slice until all slices of the set have been transferred. The debug system receives the slices and regenerates and displays the image.
