STM32 I-CODE and D-CODE buses

STM32 documentation says that the I-CODE and D-CODE buses are connected to the internal flash memory. The I-CODE bus is used to fetch instructions and the D-CODE bus is used for data access in the code memory region (literal load).

The question is why two separate buses are used? Can they provide simultaneous and absolutely independent access to flash memory?
