What does shared memory cause?
The Von Neumann bottleneck.
Von Neumann idea
| Programs stored in memory |
| Data shares the same memory |
| CPU runs one step at a time |
Remember
| Stored program concept |
| One shared path slows the CPU |
Why can one computer run so many different apps? Von Neumann's stored program idea. Programs sit in memory. Data shares that memory. The CPU runs steps one by one. It is the stored program concept. One shared path slows the CPU.
