I need to know CM403 processor belongs to which category,is it Von Neumann or Harvard architecture.
In the data sheet ADSP-CM402F_CM403F_CM407F_CM408F.pdf, in page 7,under ARM CORTEX-M4-CORE,it is mentioned that "It uses a single 32-bit bus for instruction and data".So it made me to think that it falls under Von Neumann Architecture.
However the hardware manual ADSP-CM40x_hrm_rev.0.2.pdf,in page 77,under ARM Cortex-M4-Core,it is mentioned that "The processor is built on a high-performance core, with a 3-stage pipeline Harvard architecture"
I am quite confused whether CM403 processor falls under Harvard architecture or Von Neumann architecture..?
Please clarify me.
Thanks in advance,
