1.1.1- Von Neuman And Harvard Flashcards
Van Neumann architecture
Architecture in which there is a single shared memory and instructions are stored in the same format
Harvard architecture
Architecture in which there is two separate memory and data buses for data and instructions
Contemporary processing
Modern machine in which Von Neumann is used for main memory. Cache uses Harvard, divided
Into instruction cache and data cache
What architecture uses RISC
Harvard
Which architecture was its own bus
Harvard
What happens at Harvard architecture
Reading and writing is done at the same time as fetching an instruction
Which architecture uses registers and why?
Von Neumann for faster access to instructions or data
What architecture follows linear FDE cycle
Von Neumann
What architecture has a single control unit?
Von Neumann
How does contemporary differ?
Uses SIMD and MIMD
SIMD
single Instruction Multiple data
Parallel processing where processor carries out a single instruction on multiple data items
MIMD
multiple instructions multiple data
Multiple instructions carried out on multiple data items across several cores
What is distributed computing
Multiple computers on a shared network take part In a bigger problem
E.g internet
