Meeting Consumers' Hd Demands With a Faster Algorithm


Lehigh University researchers have developed signal-processing algorithms that enable handheld devices to display high-definition images.

Mobile high-definition applications require fast processing speeds and efficient power use, says Lehigh professor Zhiyuan Yan. "To achieve the required speed, we have developed an entirely new class of algorithms that can be directly cast into hardware," says Lehigh professor Meghanad Wagh. He says the algorithms are extremely fast and take advantage of new trends in technology, such as scaling complementary metal-oxide semiconductor technology and parallel processing.

The algorithms can be scaled to handle the greater level of complexity required by computationally intensive jobs. "Our algorithms are inherently structured," Yan says. "This enables us to extract the maximum parallelism in processing and to offload tasks to dedicated hardware."
