Document Summary
Covers up to last lecture + next week"s homework & lab. Next several works: how a modern processor is built, starting with basic elements as building blocks. Understand capabilities and limitations of hw and processors in particular. What processors can do fast and what they can"t do fast. Avoid slow things if you want your code to run fast. Background for more in-depth hardware courses (eecs 151, cs 152) May need to design own custom hw for extra performance. Asynchronous systems much much much harder to design/debu. Two binary digits: 1 and 0, or true and false. Electrical signals are treated as 1"s and 0"s. These days, even a lot of analog circuitry is best done as put it through an adc, do it all digitally in a synchronous circuit, and output it to a dac. Arrow shows action if wire changes to 1 or is asserted. Compose switches into more complex ones (as boolean functions)
