It was thus said that the Great Bill McDermith once stated:
As an interesting side note, from my understanding, the MIPS
processor doesn't have a stack in the same way as the pdp-8
doesn't -- it has to be implemented "by hand", with stores
through a register (stack pointer) with the register incremented
or decremented... Of course, the MIPS has registers (note the
plural), while the pdp-8 has an accumulator.
Yes, on the MIPS, the return address is stored in a register so if the
routine you call makes further calls, that register needs to be saved, and
usually another register is used as the stack register but it's managed ``by
hand'' as it were.
As this is on topic, as MIPS chips have been around for over 10 years ...
