Abstract: Disclosed is a display device using a demultiplexer. The demultiplexer sequentially samples data currents that are multiplexed and applied by a data driver, and holds currents corresponding to the sampled data currents to a plurality of data lines. Since the demultiplexer is to sample the data currents corresponding to N data lines during a horizontal period when performing 1:N demultiplexing, the data current corresponding to one data line is to be sampled during a 1/N horizontal period. A signal line coupled between the demultiplexer and the data driver is precharged with a precharge current before sampling the data current. According to one embodiment, the precharge current is M times the data current, where M is a real number greater than 1.

The method repeats the following steps for plural iterations including loading the data buffer with new input data forming a new input data array for a next iteration and performing the input data array operation on the new input data array.

Abstract: In a multiple render target mode, a pixel shader computes color values for pixels and stores the computed color values in a register file. The register file acts as a buffer for the computed color values. Conventionally writing pixels in the order they are received (pixel-major order) can result in large strides across memory in the frame buffer. At least a minimum amount of work should be done within a DRAM page, for example, to cover the overhead required in opening the DRAM page. Therefore, color values are written from the register file to two or more targets in a frame buffer in a target-major order within a segment. Writing in a target-major order (sequential with respect to targets but non-sequential with respect to quads received and processed) yields coherent writes to frame buffer memory and improves memory efficiency.
