The root cause turns out explicitly to be because MMUs are so valuable: without one, you can’t run Linux, BSD, or Mach. Thus, when ARM split their IP portfolio into the A, R, and M-series cores, the low-cost M-series cores were forbidden from having an MMU to prevent price erosion of their high-end A-series cores. Instead, a proprietary hack known as the “MPU” was introduced that gives some memory security, but without an easy path to benefits such as swap memory and address space relocation.。关于这个话题，wps提供了深入分析

Verifying a permutation takes O(n) but sorting under the appropriate assumptions takes O(n ln(n)), so there is a complexity gap there. https://cacm.acm.org/research/program-correctness-through-self-certification/。WhatsApp Web 網頁版登入是该领域的重要参考
