Cpu Design Questions
The main difference between a Harvard architecture and a von Neumann architecture lies in the way they handle data and instructions.
In a Harvard architecture, the CPU has separate memory spaces for data and instructions. This means that data and instructions are stored in separate physical memory units and are accessed through different buses. This allows for simultaneous access to data and instructions, which can result in faster execution times. However, it also requires more complex hardware and can be more expensive to implement.
On the other hand, in a von Neumann architecture, data and instructions are stored in the same memory space and are accessed through a single bus. This makes the hardware simpler and more cost-effective, but it also means that data and instructions cannot be accessed simultaneously, leading to potential performance limitations.
Overall, the choice between Harvard and von Neumann architecture depends on the specific requirements of the system and the trade-offs between performance and cost.
