In the space industry, concurrent design is frequently implemented as requirements are frequently not set but developed along the design process. In many cases this is due to the interconnection between (sub)systems. In the industry however, this is hardly done, but it is becoming more relevant as lead times and innovation speed needs to increase.
There is a webinar tomorrow 10 december from Agile on this topic regarding the semiconductor industry
Reversible logic could cut the energy wasted by computers to zero. But significant challenges lie ahead.
By some estimates the difference between the amount of energy required to carry out a computation and the amount that today's computers actually use, is some eight orders of magnitude. Clearly, there is room for improvement.
There are one or two caveats, of course. The first is that nobody has succeeded in building a properly reversible logic gate so this work is entirely theoretical.
But there are a number of computing schemes that have the potential to work like this. Thapliyal and Ranganathan point in particular to the emerging technology of quantum cellular automata and show how their approach might be applied.
We did look at making computation powers more efficient from the bio perspective (efficiency of computations in brain). This paper was actually the base for our discussion on a new approsach to computing http://atlas.estec.esa.int/ACTwiki/images/6/68/Sarpeshkar.pdf and led to several ACT internal studies
