With Cortext-M7 600 MHz as the controller, INS8060 (SC/MP II) can run at 4MHz clock. The controller can communicate with the MPU via software UART using FLAG0 and SENSE B, which is used by NIBL Basic interpreter and Floatingpoint Basic as well. Since the controller handles every bus cycles, it can disassemble bus cycles just before halting the MPU. That is quite handy for debugging.
