It cannot utilize the arm and big risc-v core simultaneously. You can choose which one to use by jumping a gpio pin (or with a physical switch on the Duo S). The big core typically runs Linux, while the smaller core typically runs RTOS (or arduino). And using a protocol (mailman) they can communicate. The 8501 also uses mailman and can be used to wake up the rest of the system.
