A graphics system comprises a texture memory, a rendering engine, a sample buffer and a filtering engine. The rendering engine renders received primitives based on a render pixel array whose vertical and horizontal resolutions are dynamically programmable. The rendering engine determines render pixels that geometrically intersect a primitive. For each intersecting render pixel, a texture access may be required (if texture processing is turned on) to determine texture values. The texture values may be used to compute sample values at sample positions interior to the sample render pixel and the primitive. A controlling agent may decrease the vertical and horizontal resolutions of the render pixel array to control frame render time. The filtering engine may programmably generate virtual pixel centers covering the render pixel array. Any change in the render pixel resolutions may require an accommodating change in the virtual pixel array parameters.

The read-out unit (i) reads out a level of the first signal while the switch transistor is OFF, and (ii) reads out a difference between the level of the first signal and a level of the second signal when the switch transistor is turned from OFF to ON.

A graphics system reduces fetching from memory of color-key pixels when video pixels from a video-overlay window are displayed. A frame buffer is divided into multi-line, multi-pixel blocks that are arranged in block-rows and block-columns. Each block-row has primary and secondary row indicator bits and each block-column has two column indicator bits. When the primary row indicator bit is cleared, all pixels in the block-row are fetched from a frame-buffer memory. When the primary row indicator is set, a secondary row indicator bit selects either first or second column indicator bits for reading. When the selected column indicator bit for a block-column is set, fetching of pixels from the frame buffer memory is skipped. Instead, dummy color-key pixels are generated and inserted into the pixel stream. These dummy pixels match the color key and cause video pixels to be sent to the display. Memory fetching is reduced.
