do we agree that "normal" instructions (not LD/ST, not MUL/DIV)
have a latency of two clock cycles, while the throughput, given
a sequence of these instructions, is one instruction/clock cycle?

If the machine wasn't pipelined at all, the throughput would be
the reciprocal of the latency, 0.5 instructions/clock cycle.

Perhaps we have different definitions of "pipelined". What,
then, is your exact definition of a two-stage pipeline?

Best regards,
Hellwig
