Bus and Memory Hierarchies
Computer architecture and organization studies and explains the relationship between the different levels of computer systems including the bus and memory hierarchies. The bus hierarchy is that of communication components, including how data and instructions travel and how the processor communicates with the memory, or main storage. The memory hierarchy is that of storage components, including how the main memory interacts with fast-access caches and slower secondary memory systems such as hard discs.
The bus and memory hierarchies differ in speed and latency, but they can be abstracted into a single hierarchical view that studies their relation. Computer architects design, develop, and analyze these hierarchical components and their interactions to create efficient and optimized computer systems. Depending on the task and application, different bus and memory configurations are used to achieve maximum efficiency in a computer system.
The bus hierarchy is typically composed of three levels, the system bus that transfers data, the I/O bus for peripheral devices, and the memory bus that allows direct access to main memory. Depending on the task and application, the hierarchical organization of the bus and memory systems can be placed in different levels of the hierarchy, including memory buses, memory protocols, and memory interfaces.
The memory hierarchy is composed of three basic components; the main memory, the cache memory, and the secondary memory. Main memory stores instructions and data and allows for direct access by the processor. Cache memory is a level of fast-access memory that often stores recent instructions and data and helps increase system performance. Secondary memory is generally slower than cache memory and is used to store non-volatile data, such as files and programs.
