What is meant by Computer architecture and VLSI!?
Dear Sasirekha G, Computer architecture is right of what you’ve mentioned. In order to repair or design a personal computer, needs science of computer architecture. Computer architecture basicly consists of power supply, microprocessor, CMOS (BIOS: Basic Input Output System), memory (RAM/DRAM), several interfaces (monitor card, modem, etc.), input systems (keyboard, mouse, CD RW), output systems (monitor, printer, CD RW). You also need to know about 8/16/32 bits bus (terminal/slot). VLSI designed and produced when you need to do very huge (enormous) jobs/calculations with “machine” with small size. On kind of VLSI is microprocessor. I am not sure about verilog, but basicly, IC consists of several/many transistors, and electronic components, put together in simple package. IC design started with electronic circuit design that IC would like to perform. Eg. you would like to design IC to operate as simple AF amplifier. In ordinary, that circuit consists of 2 transistors, etc. After that,
Computer architecture in computer engineering is the conceptual design and fundamental operational structure of a computer system. It is a blueprint and functional description of requirements and design implementations for the various parts of a computer, focusing largely on the way by which the central processing unit (CPU) performs internally and accesses addresses in memory. It may also be defined as the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost goals. Very-large-scale integration (VLSI) is the process of creating integrated circuits by combining thousands of transistor-based circuits into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. The term is no longer as common as it once was, as chips have increased in complexity into the hundreds of millions of transistors.
