The history of computers Atmel Norway 2005
Foundation for modern computing An automatic computing machine must have: A store for the numbers (memory) A device for performing arithmetic operations (ALU) A device for causing the operations of the machine (CU) An input and output device (Mouse, keyboard, screen)www.atmel.comTromsø August 12, 20053
First Generation: The Manchester Computer The world’s first storedprogram electronic digitalcomputer Executed its first program onJune 21st in 1948. Designed and constructed byMachester University Ferranti Ltd. was given rightsto produce and sell acommercial version of themachine (Manchester markI)www.atmel.comTromsø August 12, 20054
The Most Important Step: Integrated Circuits The introduction ofintegrated circuits led to thethird generation ofcomputers Mini-machines made out oflogic gates Small scale integratedcircuitswww.atmel.comTromsø August 12, 20055

The future Atmel Norway 2005
Trends into the future Shrink Size decrease will continue Lower production cost and end user price Lower power Today 1.8V operation 1 Li cell or 2 AA/AAA batteries to run0.9V technology will be introduced 1 AA/AAA battery to run On-chip debug The end of expensive in-circuit emulators Open source Linux OS User interaction. www.avrfreaks.netwww.atmel.comTromsø August 12, 200525
