Researchers have developed FPGAFly, a system capable of simulating the entire 166.7k-neuron fruit-fly (Drosophila) central nervous system on a single field-programmable gate array (FPGA). This was achieved through novel techniques like order-preserving deferred spike expansion and a 24-bit encoding for neuron states, which significantly reduced memory traffic and on-chip memory usage. The system successfully simulated the Drosophila CNS connectome, completing a 100ms window simulation in under 94ms on a Gowin GW5AST-LV138 FPGA, and was also tested on 10,000 MNIST predictions. AI
