no2chem | 0:b5d3bd64d2dc | 24 | Topic: Description |
no2chem | 0:b5d3bd64d2dc | 25 | Simple state machines like this one are used in many embedded products. |
no2chem | 0:b5d3bd64d2dc | 26 | |
no2chem | 0:b5d3bd64d2dc | 27 | For more complex state machines, sometimes a state transition table implementation is used instead, |
no2chem | 0:b5d3bd64d2dc | 28 | trading speed of direct coding for ease of maintenance. |
no2chem | 0:b5d3bd64d2dc | 29 | |
no2chem | 0:b5d3bd64d2dc | 30 | Since the main goal of using a state machine in CoreMark is to excercise the switch/if behaviour, |
no2chem | 0:b5d3bd64d2dc | 31 | we are using a small moore machine. |
no2chem | 0:b5d3bd64d2dc | 32 | |
no2chem | 0:b5d3bd64d2dc | 33 | In particular, this machine tests type of string input, |
no2chem | 0:b5d3bd64d2dc | 34 | trying to determine whether the input is a number or something else. |
no2chem | 0:b5d3bd64d2dc | 35 | (see core_state.png). |
