Traditional computers follow the "Von Neumann" architecture, where instructions and data share the same pathway. For DSP tasks, this is like trying to drive a sports car through a one-lane tunnel—it's too slow. Avtar Singh’s architecture focuses on the Harvard Architecture, which uses separate pathways for data and instructions, allowing the processor to "read" and "do" at the same time.
