There looks to be more BOM cost given to PSU functions than anything else, after the CPU. Of course the PSU earns its keep by getting max battery life from this CPU/display/memory but switchers are also a source of EMI, control of which adds more components. I look forward to wide-range 200MHz converters with built-in L and C, sold in such huge qties that the cost is negligible, like the old 78xx series.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
