@lupyuen Interesting, but there are some strange things in this article:
* ESA already uses RISC-V processors for space due to its efficiency
* He probably missed the RISC-V V extension that was drafted for years, and ARM Cortex-A53 as far I know has only SIMD functions, no Vector procssor ?: "Interestingly, Cannizzaro's analysis suggests that RISC-V does not in fact offer the best performance characteristics. ARM Cortex-A53 achieved this distinction thanks to its vector capabilities, which RISC-V currently lacks."
