Presentation transcript:

A Look Inside The Processor Architecture Determines Location of CPU parts Bit size Number of registers Pipelines Main difference between CPUs

Microcomputer Processors Intel Leading manufacturer of processors Intel 4004 was worlds first microprocessor IBM PC powered by Intel 8086 Current processors Centrino Itanium Pentium IV Xeon

Microcomputer Processors Advanced Micro Devices (AMD) Main competitor to Intel Originally produced budget products Current products outperform Intel Current processors Sempron Athlon FX 64 Athlon XP

Microcomputer Processors Freescale A subsidiary of Motorola Co-developed the Apple G4 PowerPC Currently focuses on the Linux market

Microcomputer Processors IBM Historically manufactured mainframes Partnered with Apple to develop G5 First consumer 64 bit chip

Comparing Processors Speed of processor Size of cache Number of registers Bit size Speed of Front side bus

Extending The Processors Power Standard computer ports Keyboard and mouse ports USB ports Parallel Network Modem Audio Serial Video

Standard Computer Ports

Extending The Processors Power Serial and parallel ports Connect to printers or modems Parallel ports move bits simultaneously Made of 8 – 32 wires Internal buses are parallel Serial ports move one bit Lower data flow than parallel Requires control wires UART converts from serial to parallel

Serial Communications

Parallel Communications

Extending The Processors Power USB Universal Serial Bus Most popular external bus Supports up to 127 devices Hot swappable

Extending the Processors Power FireWire IEEE 1384 Cameras and video equipment Hot swappable Port is very expensive

Extending the Processors Power Plug and play New hardware detected automatically Prompts to install drivers Non-technical users can install devices
