Twenty five years later, the microprocessor is the most complex mass-produced product ever, with more than 5.5 million transistors performing hundreds of millions of calculations each second. A microprocessor is an integrated circuit that lies at the heart of every personal computer. Decode -decides what the instruction means. Execute -carries out the instruction. A modern microprocessor can repeat this three-step process many millions of times in one second.
Students give directions to each other.
Lesson Plan 1. Briefly review the ideas that a microprocessor works rapidly and accurately, but does not think. Divide students into small groups. Provide at least one copy of the Programming a Walking Robot handout to each team. Give the groups time to browse through the handout.
