Internal architecture
The FR-family CPU has a Harvard architecture in which the instruction bus and data buses are separated. The
32-bit
←→16-bit bus converter is connected to a 32-bit bus (F-bus) , providing an interface between the CPU
and peripheral resources. The Harvard
←→Princeton bus converter is connected to both of the I-bus and D-bus,
providing an interface between the CPU and the bus controller.
