processor is the main component of SBC. Hence it is essential to know the type of the processor‚ processing speed etc. for a particular application. For eg‚ in an industrial environment where the importance is given to ruggedness of the box rather than the CPU performance‚ the preference would be fanless processors like those from Intel (Atom) and VIA. But for billing systems which needs more processing power‚ SBC may require a dual port or higher performance processor.ARM which was prevalent on handset

illustrate the basic concepts of processing input and output. The basic architecture is comprised of a little man in a small room that performs basic tasks. The little man executes basic tasks by following a set of instructions. The main components of the LMC are mailboxes‚ calculator‚ inbox‚ and outbox. Like in a real computer‚ the memory in the LMC consists of mailboxes which are slots to hold stored information. The calculator is like the Arithmetic Logic Unit on a real computer‚ and the inbox

process. Therefore‚ although two processes may be associated with the same program‚ they are nevertheless considered two separate execution sequences. It is common to have a program that spawns many processes as it runs. Note: A process is the unit of work in a system. • Such a system consists of a collection of processes‚ some of which are operating-system processes (those that execute system codes) and the rest of which are user processes (those that

address is a virtual address or a register. Register indirect addressing uses the same number of memory references as indirect addressing. The memory transfer rate has kept up with increases in processor speed. The control unit (CU) does the actual computation or processing of data. The processor needs to store instructions and data temporarily while

A Brief History of Intel’s desktop processor CPU is the most important part in computers. If compared to a person‚ computer’s heart is CPU. Processing information in accordance with its word length‚ CPU can be divided into: 4-bit processors‚ 8-bit processors‚ 16-bit processors‚ 32-bit processors and 64-bit processors‚ etc. Intel Corporation was founded in 1968‚ and then became a leader of the IT Industry. November 15th‚ 1971‚ Intel’s engineer Hoff invented the world’s first commercial
