They can still be diverse to leverage certain strengths as long as there's enough compatibility that you don't have to rewrite everything from scratch. I'm hopeful for lowRISC as the spiritual successor to BS-5000 and i960.
- nickpsecurity 10y agoPotentially. Far as successors, look up crash-safe.org and Cambrige's CHERI processors. Those are cutting-edge successors to tagged (i.e Burroughs) and capability (i.e. i960, Sys38). Draper is adding SAFE's PUMP to a RISC-V corr they plan to open-source and turn into an ecosystem. CHERI is OSS plus already runs a FreeBSD port called CHERIBSD. That CHERI supports legacy, C software and runs BSD means it's ahead. I considered porting EROS capability system, GenodeOS, or Muen to CHERI. Plus cutting it down from 256-bit to 128-bit pointers as the extra bits are just there for experimentation.
