Researchers in the ラーメンベット 禁止ゲーム of ラーメンベット 口コミ are in the midst of a yearslong effort to build the processors that could power next-generation technologies, such as driverless cars and automated manufacturing. And they have just created a fresh take on a key building block of this new crop of chips that promises increased computing speed and superior energy efficiency.
In a paper recently published ラーメンベット 口コミ journal Nature Communications, the researchers present a demonstration for a silicon-integrated, photonics-based electronic-photonic arithmetic logic unit. Arithmetic logic units are important components of a processor that perform all the calculations for CPUs.
The discovery is part of a larger .5 million project sponsored by the U.S. Air Force Office of Scientific Research and led by electrical and computer ラーメンベット 口コミ professors Ray Chen and Dave Z. Pan. The project aims to create a myriad of ultra-low power nano-optoelectronic devices, to reduce processor power consumption and latency while boosting speed.
Due to the saturation of Moore's Law — the decades-long trend of computers becoming faster and less expensive over time by packing more transistors into a single chip — researchers are looking for new ways to make ラーメンベット 口コミ more powerful. This project is built on the increasingly popular concept of optical ラーメンベット 口コミ in both digital and neuromorphic ラーメンベット 口コミ, which uses photons rather than electrons to transport and process information. Optical ラーメンベット 口コミ can utilize dense wavelength division multiplexing (DWDM) for more efficient processors that can more effectively use the integrated photonic circuits and components. This unleashes the potential for next-level ラーメンベット 口コミ.
"Our optical ラーメンベット 口コミ devices have demonstrated speed beyond state-of-the-art processors, using much less power with lower latency, which means you can build a much faster computer that is more energy-efficient," Chen said.
The new logic units will allow the team's chips to achieve processing speeds of more than 20GB per second, more than four times the speed of today's best electronic counterparts. The ラーメンベット 口コミ aim to use only 30% of the energy consumed by their current contemporaries, while reducing latency by 10 to 100 times.
The team’s silicon chip was designed at UT Austin with and then fabricated at the American Institute for Manufacturing, a federal consortium for nanofabrication. Chen compared the process of fabricating computer chips to building skyscrapers, but on a nano scale. Each layer ラーメンベット 口コミ processor — similar to a floor in a building — must sit precisely on top ラーメンベット 口コミ last. The smallest mistake can bring the whole structure tumbling down.
"Alignment is critical," Chen said. "If one layer has one micron of deviation, the whole process fails. The inaccuracy will demolish all ラーメンベット 口コミ efforts."
