Computer Architecture Examples and Hierarchy

Hierarchy. Layers of components made out of smaller partsA higher layer will abstract the immediate lower layerWe can design complex systems using higher abstraction layer without worrying about the individual components of the lower layersCan be used in both hardware as well as software. Example

    1. Computer Architecture Examples and Hierarchy By Cheuk Wong

    2. Hierarchy Layers of components made out of smaller parts A higher layer will abstract the immediate lower layer We can design complex systems using higher abstraction layer without worrying about the individual components of the lower layers Can be used in both hardware as well as software

    3. Example of Software hierarchy From Highest to Lowest Applications: MS Powerpoints, Firefox, etc High level program languages: Java, C/C++, etc Interpreted Languages: LISP, ProLog Assembly Languages: x86 Machine Code: Binaries Flip-flips and Logic Gates Transistors We can work with any of the layers without knowing how the lower layers work.

    4. Hardware Hierarchy From Highest to Lower Computer System: Monitor, keyboard, “black box” Integrated Circuit: CPU, Memory system Chip Level: ALU, Registers, Cache, RAM Flip-flops, Multiplexers, Decoders, Adders NOT-gate, AND-gate, NAND-gates, OR-gates, NOR-gate MOSFET Transistors, NPN-Transistors, PNP-Transistors Again, we can work with any layers without worrying about the lower layers.

    5. Some more Hierarchy Again, from highest to lower Internet LAN, PAN Computer Systems Moving on to Computer Architectures...

    6. Computer Architectures Computer Architectures is the conceptual design and fundamental operational structure of a computer system -Wikipedia Deals with the Integrated Circuit and Chip Level layers of the Hardware Hierarchy Mainly focuses on how the CPU interact with other parts of the computer, such as accessing main memory or interfacing with peripheral hardwares Ultimate goal is to increase performance

    7. Subcategories of Comp. Arch. Instruction Set Architecture (ISA): Provide a set of language structure and data type Ex. x86 Will not be discussed since this is cover in CS47 Micro-architecture: Describes how multiplexers, decoders, adders, transistors, etc interact with each others. The ISA will be depended on Micro-arch is designed. System Design: Describes how all the hardwares are connected to each other (e.g. buses, memory controller, etc)

    8. Micro-architecture Describes how multiplexers, decoders, etc are connected to each other.
