What is an ARM Processor? ARM Processor The ARM microcontroller stands for Advance Risk Machine; it is one of the extensive and most licensed processor cores in the world. The first ARM processor was developed in the year 1978 by Cambridge University, and the first ARM RISC processor was produced by the Acorn Group of Computers in the year 1985. These processors are specifically used in portable devices like digital cameras, mobile phones, home networking modules and  wireless communication technologies  and other  embedded systems  due to the benefits, such as low power consumption, reasonable performance, etc. This article gives an overview of ARM architecture with each module’s principle of working. ARM Architecture The ARM architecture processor is an advanced reduced instruction set computing [RISC] machine and it’s a 32bit reduced instruction set computer (RISC) microcontroller. It was introduced by the Acron computer organization in 1987. This ARM...

What is Pipelining? In computer networking, pipelining is the method of sending multiple data units without waiting for an acknowledgment for the first frame sent. Pipelining ensures better utilization of network resources and also increases the speed of delivery, particularly in situations where a large number of data units make up a message to be sent. Flow Diagram of Pipelined Data Transmission The following flow diagram depicts data transmission in a pipelined system versus that in a non-pipelined system. Here, pipelining is incorporated in the data link layer, and four data link layer frames are sequentially transmitted. Data Link Protocols that uses Pipelining Two data link layer protocols use the concept of pipelining − Go – Back –  N Go – Back –  N  protocol provides for pipelining of frames, i.e. sending multiple frames before receiving the acknowledgment for the first frame. The frames are sequentially numbered and a finite number of frames ar...
