The original 8051 core ran at 12 clock cycles per machine cycle, with most instructions executing in one or two machine cycles.

Provided that not more instructions were executed than the indicated maximum number of machine cycles video memory could be accessed during the interrupt routine.
25.
Program steps execute in one machine cycle, except for steps performing multiplication or division which take as many machine cycles as needed for the operation.

It also means that a higher frequency crystal must be used than without this subdivision of machine cycles ( approximately 2 3 times higher ).
28.
In contrast, enhanced 8051 silicon IP cores now run at one clock cycle per machine cycle, and have clock frequencies of up to 450 MHz.
29.
The Z80 machine cycles are sequenced by an internal state machine which builds each M-cycle out of 3, 4, 5 or 6 T-cycles depending on context.
30.
Tab machines programs were executed by impulses emitted in a machine cycle; hence, FARGO and RPG emulated the notion of the machine cycle with the program cycle.
