Great article and just a little reminder. The old fashioned embedded system developers are still using a similar way of programming, for example, when it comes to 8031/8051 or even some newer chips like TI DSP TMS320C5416, TMS320C2407, you can still programming everything manually. For example, when using float numbers in a C5416 (a fixing-point dsp chip), one has to remember where is the point of the float number and a division has to be carefully designed and optimized.
