The number of transfers per clock cycle is dependent on the technology used.
During the first clock cycle, we need to actually load the instruction.
The patch also uses less clock cycles than the original.
The advantage is to bring the system to a known state without going through many clock cycles.
The processor could only communicate with the rest of the system on every other clock cycle.
All jumps and calls take at least 15 clock cycles.
The effect of this signal is actually delayed by one clock cycle.
As a result the interrupt overhead was only 3 clock cycles.
The article said execution takes on clock cycle to complete.
In some cases, more than one clock cycle is required to perform a predictable action.
