The ARP32 CPU has a single clock domain (cpu_fclk) and two reset domains:
Both of the reset signals are used asynchronously inside the design. Both the leading and trailing edges of these reset signals are synchronized with the CPU input clock by the external clock/reset management logic.
To reduce dynamic power consumption, the ARP32 CPU gates all of its internal clocks based on debugger connection status and CPU idle/standby status:
