However, as a pragmatic system architect, I see no reason to eschew the MMU in favor of any of these. In fact, the MMU is composable with all of these primitives – it’s valid to have both a PMP and an MMU in the same RISC-V CPU. And, even if you’re using a CHERI-like technology for hardware-enforced bounds checking on pointers, it still doesn’t allow for transparent address space relocation. Without page-based virtual memory, each program would need to be linked to a distinct, non-overlapping region of physical address space at compile time, and you couldn’t have swap memory.

The SPARCstation IPC and IPX share the same power supply and this web page gives a description of replacing the electrolytics in a PSU from an IPC. Interestingly, the author notes elsewhere that they had two IPCs with dead PSUs, whereas one fitted in an IPX worked fine. However, the IPC is a slightly earlier model and it could simply be that these were older, else perhaps pure chance. In any case, I have two IPXs and both of which with suffered from dead power supplies.，详情可参考新收录的资料
