Deep learning accelerators comparable to GPUs, FPGAs, and extra recently TPUs. Started in 1943, the ENIAC computing system was built by John Mauchly and J. Presper Eckert on the Moore School of Electrical Engineering of the University of Pennsylvania. Due to its digital, versus electromechanical, know-how, it is over 1,000 occasions sooner than any previous computer. ENIAC used panel-to-panel wiring and switches for programming, occupied more than 1,000 square toes, used about 18,000 vacuum tubes and weighed 30 tons. It was believed that ENIAC had achieved more calculation over the ten years it was in operation than all of humanity had till that point.
