Embedded-system programmers must learn the fundamentals

The diminishing effect of the Moore's Law on processor performance that produces inefficient and disorganized code is being a problem for embedded-system programmers. Moore's Law does not predict performance that will double every couple of years, it predicts only that the number of transistors in an IC will double every two years. It is suggested that when designing a software at a system level, performance issues should always be considered from the beginning. Programmers can wisely choose which high-level language statements produce the best possible machine statements and produce the best possible machine-in-instruction sequence by understanding the ways the CPUs execute machine-level code and compilers translate high-level source statements. .
