Different Processors 5 B 2
Microcomputer Processors Intel ◦ Leading manufacturer of processors ◦ Intel 4004 was worlds first microprocessor ◦ IBM PC powered by Intel 8086 ◦ Current processors Centrino Itanium Pentium Xeon Core i 3, i 5, i 7 Core v. Pro: Business comp & Intelligent 5 B 3
Microcomputer Processors Advanced Micro Devices (AMD) ◦ Main competitor to Intel ◦ Originally produced budget products ◦ Current products outperform Intel ◦ Current processors Sempron Athlon FX 64 Turion Phenom AMD A-Series (A 4, A 6, A 8, A 10) AMD FX 8 -Core, 6 -Core, 4 -Core 5 B 4
Microcomputer Processors Freescale ◦ A subsidiary of Motorola ◦ Co-developed the Apple G 4 Power. PC ◦ Currently focuses on the Linux market 5 B 5
Microcomputer Processors IBM ◦ Historically manufactured mainframes ◦ Partnered with Apple to develop G 5 First consumer 64 bit chip 5 B 6
Comparing Processors Speed of processor Size of cache Number of registers Bit size Speed of Front Side Bus (FSB) 5 B 7
Advanced Processor Topics RISC processors ◦ Reduced Instruction Set Computing ◦ Smaller instruction sets ◦ May process data faster ◦ Power. PC and G 5 5 B 8
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 5 B 9
Extending The Processors Power Standard computer ports ◦ Keyboard and mouse ports ◦ USB ports ◦ Parallel ◦ Network ◦ Modem ◦ Audio ◦ Serial ◦ Video ◦ HDMI 5 B 10
Standard Computer Ports 5 B 11
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 A computer chip called UART (Universal Asynchronous Receiver-Transmitter) converts parallel computer data into serial output 5 B 12
Serial port 5 B 13
Serial Communications 5 B 14
Parallel Communications 5 B 15
Parallel Port 5 B 16
