    I asked grok to describe a union of bit field structs that maps correctly all RV32I instructions and the respective bit fields... but I was surprised that some friends never had saw bit fields before, although it was part of original K&R, back in 1978! 😁 x.com/i/grok/share/p…

    Harvard vs. von Neumann on #DarkRISCV: w/ Harvard there are two concurrent buses Yxxx for instructions and Xxxx for data, resulting in CPI=1.62, while w/ von Neumann they are time multiplexed to a single bus, resulting in a CPI=4.82, both w/ BRAM and no-caches! 🔥

    #riscv is just cheap as sand! but be careful: 4.95$ for 50 pieces! so order "10" will result in 500 devices! 🔥 aliexpress.com/item/100500503…

    already posted here, but never gets old: the future of programming are neural networks on 10 cent processors! small problems on small devices, no need for a GPU everywhere…🔥 cpldcpu.wordpress.com/2024/04/24/imp…
