Computer Architecture

The processor is the main computing unit of any computer. The processor is a digital circuit made of a silicon chip that performs computation within a fraction of a second. The speed of a processor is measured in terms of megahertz (MHz). The term processor is often used interchangeably with the term CPU, i.e. central processing unit. Although the CPU is not the only … [Read more...] about Types of Processors

Array processor in computer architecture has multiple arithmetic logic units that enhance the system's performance. Majorly there are two types of array processors available: Attached Array Processor SIMD Array Processor The array processor is one of the approaches to parallel computers. What is Parallel Computer? A parallel computer has multiple processing … [Read more...] about Array Processor in Computer Architecture

Assembly language in a computer is a low-level programming language. The assembly language (ASM) is close to hardware and has direct control over it. But it is far different from machine language. ASM is easily readable by humans. ASM programs are processed by an assembler and converted to machine language. The ASM program consists of a sequence of statements, each … [Read more...] about Assembly Language in Computer

Control signals regulate the operations and coordination of all processor components while executing the instructions. It is the control unit of the CPU, which is responsible for generating control signals. If we divide the instruction cycle into two phases, it would be the fetch phase and the execution phase. Even the processor’s hardware is divided into two sections. The … [Read more...] about Control Signals in Computer Architecture

Memory hierarchy describes how the computer organizes the memory devices based on their speed, size and cost per bit. The various memory devices we use to design a system are registers, cache memory, main memory, and magnetic disks. All these memories operate at different speeds and have different costs per bit. Why Memory Hierarchy? How much memory (size) of each kind will … [Read more...] about Memory Hierarchy in Computer Architecture
