Recently, researchers at the University of Pennsylvania published a paper saying that they have developed a powerful new optical chip, which can process nearly 2billion images per second. The device consists of a neural network that can process information into light without slowing down the components of traditional computer chips.
The chip is based on neural network, which is a system modeled on the way the brain processes information. These networks are composed of interconnected nodes like neurons, which "learn" in a way similar to the organic brain by training the data set, such as recognizing objects in images or words in speech. As time goes on, their learning ability becomes better. During the test, the team made a chip with a size of 9.3 mm2 (0.01 in2) and used it to classify a series of handwritten characters similar to letters. After training the relevant data sets, the chip can classify the images containing two character sets, with an accuracy of 93.8%, and the classification accuracy of four types of images is 89.8%. The most exciting thing is that the chip can classify each character in 0.57 nanoseconds, enabling it to process 1.75 billion images per second. The team said that this speed comes from the chip's ability to process information into light, which gives it a certain advantage over existing computer chips. Another advantage is that the chip does not need to store the information being processed, so it does not have to send data to the memory card. The research team said that it is safer not to store data because it can prevent any possible leakage.The team plans to expand the chip scale and adjust the technology to handle other types of data.
