Bus Structures in (Computer Architecture and organization)

•There are many ways to connect different parts inside a computer together.

•  A group of lines that serves as a connecting path for several devices is called a bus.

•  Address/data/control lines

 

• Multiprocessor computer

  - Execute a number of different application tasks in parallel

  - Execute subtasks of a single large task in parallel

  - All processors have access to all of the memory – shared-memory multiprocessor

  - Cost – processors, memory units, complex interconnection networks

 

• Multicomputers

  - Each computer only have access to its own memory

  - Exchange message via a communication network – message-passing multicomputers
