Graduate student Michael Tomlinson<\/strong> and undergraduate Joe Li<\/strong> have tapped into the promise of natural language prompts and ChatGPT4 in a pioneering new approach to creating a neuromorphic spiking neural network chip for machine learning and AI.<\/p>\n

Through step-by-step natural language prompts to ChatGPT4, starting with instructions to create the spiking behavior of a single biological neuron and then linking more to form a network, they generated a full chip design that could be fabricated to build a larger network chip that abstracts the functionality of neurons in the human brain.<\/p>\n

Tomlinson believes this is the first AI chip that is designed by a machine using natural language processing.<\/p>\n

\u201cThe process can be likened to giving instructions to a computer, such as \u2018Create an AI neural network chip,\u2019 and the computer generates a file containing the specifications and design for manufacturing that chip,\u201d says Tomlinson, who worked closely on the project with Li and with Andreas Andreou<\/strong><\/a>, a professor of electrical and computer engineering who is also co-founder of the Center for Language and Speech Processing<\/a> and is affiliated with the Kavli Neuroscience Discovery Institute<\/a> and JHU\u2019s new Data Science and AI Institute<\/a>. The team\u2019s design appears on the preprint site arXiv.<\/p>\n

Tomlinson explains that their design was simple as a proof of concept. The chip\u2019s final network architecture is a small silicon \u201cbrain\u201d with two layers of interconnected neurons. It has a flexible programming system, featuring an 8-bit addressable weight system to program the chip and fine-tune the chip\u2019s behavior. This customization is facilitated through a user-friendly interface, akin to a remote control.<\/p>\n

Before manufacturing, the team validated the chip design extensively through software simulations to ensure functionality and address any issues. Then they submitted the design electronically to the Sky water \u201cfoundry,\u201d a chip fabrication service in Minnesota, where it is currently being \u201cprinted\u201d using a relatively low-cost process.<\/p>\n

\u201cWhile a small step, this shows AI can create advanced hardware to accelerate the development of technology,\u201d says Tomlinson, noting that neural network chips could soon power energy-efficient, real-time machine intelligence for next-generation embodied systems like autonomous vehicles and robots. Tomlinson\u2019s research interests are in building systems to solve the computational problems posed by today\u2019s cutting-edge algorithms, particularly for AI. \u201cThese algorithms are getting more expensive to compute,\u201d he says. \u201cI would like to rethink how we architect our computing systems to more efficiently implement these algorithms and solve problems that people care about.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
