Learning process

3.1 Historical view (textbook p103-p105)

1978 8086 29K transistors to 2008 Corei7 781M transistors (38% per annum, doubling every 26 months)

3.2 Program Coding (textbook p105-p110)

Increasing the level of optimization will make the final program run faster, but the compilation time may be longer and debugging tools will be more difficult to debug.

3.2.1

Isa describes the behavior of the program as if each instruction was executed sequentially.
