Required Snark shares a report from Tom's Hardware: A group of Chinese scientists has published (PDF) a paper titled "Pushing the Limits of Machine Design: Automated CPU Design with AI." The paper details the researchers' work in designing a new industrial-scale RISC-V CPU in under 5 hours. It is claimed this AI-automated feat was about 1000x faster than a human team could have finished a comparable CPU design. However, some may poke fun at the resulting AI-designed CPU performing approximately on par with an i486.
Training consisted of observing a series of CPU inputs and outputs. The scientists generated a Binary Speculation Diagram (BSD) from this I/O and leveraged principles of Monte Carlo-based expansion and Boolean functions to hone the accuracy and efficiency of the AI-based CPU design. Thus the CPU design was formed "from only external input-output observations instead of formal program code," explains the scientists. It also boasted an impressive 99.99999999999% accuracy. Using the above-outlined process, an automated AI design of a CPU was created.
The taped-out RISC-V32IA instruction set CPU was fabricated at 65nm and could run at up to 300 MHz. Running the Linux (kernel 5.15) operating system and SPEC CINT 2000 on the AI-generated CPU validated its functionality. In Drystone benchmarks, the AI-generated CPU performed on par with an i486. Interestingly, it appears to be a little bit faster than an Acorn Archimedes A3010 in the same test. Though some might be unimpressed by the performance of the AI-generated CPU, the scientists also seem quite proud that their generated BSD "discovered the von Neumann architecture from scratch."
