Programming Style
Programming style is just as important as any other parameter that goes into a coding task. Here are a few ideas, rants, and raves.
Extreme Embedded
Engineering: n. The application of mathematical and scientific principles to practical ends, as the design, construction and operation of economical and efficient structures, equipment and systems. (Webster's II New Riverside University Dictionary, 1984)
Deconstructing XP
Scrum, XP, TDD, FDD, DSDM, PSP, RUP and so many other acronyms that describe various development processes pepper the literature of software engineering. Sometimes it feels like we're as subject to fads as the fashion industry. Most fall under the general moniker of "agile development", a decade-old movement that's pushing against traditional big up front design (BUFD).
Real Time Programming
Quick - come up with a one-sentence definition of "embedded"! With embedded PCs becoming common, and even MIPs chips buried into inexpensive consumer products, "embedded" is a term whose meaning is ever more nebulous.
So too for the designation "Real Time", a term whose meaning is more in the mind of the beholder than cast in linguistic concrete. In fact, the community recognizes this confusion by defining two sorts of real-time - "hard" and "soft".
An Intro to DSP
Perhaps one of the last bastions of old-fashioned embedded design is one of the newest, hottest fields: Digital Signal Processors. DSP developers still tune their code for every last bit of performance, squeezing astonishing algorithms into sometimes tiny memory spaces.
