Please give me some examples. RISC-V is the future of computing hardware Open-Source CPU specification that gets more and more traction around the world starting from tiny MCU like ESP32-C3 or ESP32-C6 (WiFi and BLE capable), along with dedicated IC for mass storage controllers (used by WD and Seagate for instance), along with OS capable running devices (more powerful than rPI), ending up at highly experimental designs that you can run yourself on FPGA and will serve to design 1000 core CPU, neural networks accelerators, building satellites and space ship onboard systems, 128-bit+ architectures, etc etc. RISC-V as Open-Source design has no boundaries, no limitations, is no subject to politics and no single group of influence/interest. Due to lack of restrictive licensing resulting MCU/CPU chip is a lot cheaper and thus accessible (i.e. ESP32-C3 RISC-V BLE and WiFi MCU cost around $0.6/piece compared to $3/piece ARM Cortex-M0+ with BLE and no WiFi and a magnitude smaller memory). We may not fix the past but we can prepare for the future :-) https://riscv.org/about/ https://riscv.org/exchanges/boards/ https://riscv.org/risc-v-developer-boards/ https://www.sifive.com/boards https://www.starfivetech.com/en/site/boards https://pine64.com/product/star64-model-a-8gb-single-board-computer/ https://riscv.org/news/2022/09/nasa-selects-sifive-and-makes-risc-v-the-go-= to-ecosystem-for-future-space-missions-sifive-business-wire/ https://riscv.org/news/2020/12/et-soc-1-chip-with-more-than-1000-risc-v-cor= es-aimed-at-accelerating-machine-learning-abhishek-jadhav-hackster-io/ https://arstechnica.com/gadgets/2021/06/sifives-brand-new-p550-is-one-of-th= e-worlds-fastest-risc-v-cpus/ https://ieeexplore.ieee.org/search/searchresult.jsp?newsearch=3Dtrue&queryT= ext=3Drisc-v --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
