- 2. Chapter 5B Modern CPUs
- 3. A Look Inside The Processor Architecture Determines Location of CPU parts Bit size Number of registers Pipelines Main difference between CPUs
- 4. 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
- 5. 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
- 6. Microcomputer Processors Freescale A subsidiary of Motorola Co-developed the Apple G4 PowerPC Currently focuses on the Linux market
- 7. Microcomputer Processors IBM Historically manufactured mainframes Partnered with Apple to develop G5 First consumer 64 bit chip
- 8. Comparing Processors Speed of processor Size of cache Number of registers Bit size Speed of Front side bus
- 9. Advanced Processor Topics RISC processors Reduced Instruction Set Computing Smaller instruction sets May process data faster PowerPC and G5
- 10. Advanced Processor Topics Parallel Processing Multiple processors in a system Symmetric Multiple Processing Number of processors is a power of 2 Massively Parallel Processing Thousands of processors Mainframes and super computers
- 11. Extending The Processors Power Standard computer ports Keyboard and mouse ports USB ports Parallel Network Modem Audio Serial Video
- 13. Extending The Processors Power Serial and parallel ports Connect to printers or modems Parallel ports move bits simultaneously Made of 8 – 32 wires Internal busses are parallel Serial ports move one bit Lower data flow than parallel Requires control wires UART converts from serial to parallel
- 16. Extending The Processors Power SCSI Small Computer System Interface Supports dozens of devices External devices daisy chain Fast hard drives and CD-ROMs
- 17. Extending The Processors Power USB Universal Serial Bus Most popular external bus Supports up to 127 devices Hot swappable
- 18. Extending the Processors Power FireWire IEEE 1384 Cameras and video equipment Hot swappable Port is very expensive
- 19. Extending the Processors Power Expansion slots and boards Allows users to configure the machine Slots allow the addition of new devices Devices are stored on cards Computer must be off before inserting
- 20. Extending the Processors Power PC Cards Expansion bus for laptops PCMCIA Hot swappable Small card size Three types, I, II and III Type II is most common
- 21. Extending the Processors Power Plug and play New hardware detected automatically Prompts to install drivers Non-technical users can install devices
