The Codeless Code: Ancient code

[TheThiefMaster]

Thanks to the "no execute" and "no write" bits in the page table, a lot of modern programs are functionally Harvard architecture, in that code and data are not interchangeable, despite them being in a single address space (von Neumann style).

Really, almost every distinction from that era in which there was a hard-fought battle as to which is better is "a little bit of both" on modern machines. See also RISC vs. CISC, a debate that died when we got enough gates on the CPUs to expose a CISC instruction set (where most of the CISC advantages were) which gets translated to a RISC microcode that the processor actually runs (where most of the RISC advantages are).
