Harvardarkkitehtuuria
Harvardarkkitehtuuria is a computer architecture concept that separates instruction and data pathways. This means that instructions and data can be fetched simultaneously, leading to faster processing speeds compared to a Von Neumann architecture, which uses a single pathway for both. In a Harvard architecture, there are two distinct memory spaces, one for instructions and one for data, each with its own bus. This separation allows for parallel access.
The concept originated at Harvard University, hence the name. Early microcontrollers and Digital Signal Processors (DSPs)
