In computing , an arithmetic logic unit ALU is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. It is a fundamental building block of many types of computing circuits, including the central processing unit CPU of computers, FPUs, and graphics processing units GPUs. The inputs to an ALU are the data to be operated on, called operands , and a code indicating the operation to be performed; the ALU's output is the result of the performed operation.
Memory-CPU single communication channel bottleneck of the von Neumann architecture is quickly stalling the growth of computer processors. A probable solution to this problem is to fuse processing and memory elements. A simple low latency single on-chip memory and processor cannot solve the problem as the fundamental channel bottleneck will still be there due to the logical splitting of processor and memory. This makes the ARAM cells capable of executing instructions in parallel. It is also asynchronous and hence reduces power consumption significantly.
The basis of comparison include: Description, dependency, function and design. It performs all processes related to arithmetic and logic operations that need to be done on instruction words. In some processors, the arithmetic logical unit is divided into two units, an arithmetic unit AU and a logic unit LU. The ALU is typically designed in such a way that it has a direct input and output access to the processor main memory —the random access memory RAM. Now, the input and outputs flow along an electronic path that is known as a bus. The input consists of an instruction word that contains an operation code or sometimes a format code.

Processors produce heat, so they are covered with a heat sink to keep them cool and running smoothly. Short Notes About Central Processing Unit Central Processing Unit-All the work done on the computer It is the part of the computer, in which Arithmetic and Logical operations are executed and instructions are instructed and decoded and executed. It consists of an arithmetic and logic unit ALU , a control unit, and various registers. One computer that looks pretty cool has a bit quad-core Intel i7 3. RAM Disk is used to provide extra memory for program data storage. The computer's central processing unit CPU is the portion of a computer that retrieves and executes instructions. So you're shopping for a new computer in an electronics store and you're trying to make sense of the technical specifications.
The terms and definitions in the study of computer system are: Hardware: The physical parts of a computer system called as hardware. Computer hardware refers to the physical parts or components of a computer such as the monitor, mouse, keyboard, computer data storage, hard drive disk HDD , system unit graphic cards, sound cards, memory, motherboard and chips , etc. Any part that we can see or touch is the hard ware.
