Most software products exibit all kinds of similar behaviors to his "A-G" list. The "pure coincidence" thing is how most libraries work in your code.
However, software is usually evolved rapidly to avoid triggering design problems.
The solution should perhaps be moving more things off hardware and into software.
- CHY872 12y agoWhat things would you move off hardware and into software? Typically the reason why we produce something in hardware is because it's infeasible to do in software. This is because of the costs mentioned.
- guard-of-terra 12y agoI imagine we can have SOC of CPU+RAM in one package and save on their wiring, for example.
- Kliment 12y agoTypically you'll use PoP with modern SoCs, where you put the memory on top of the CPU so connections don't go through the PCB
- kabouseng 12y agoPlace FPGA blobs down, now you have hardware like software components. But not an option for battery powered products, because of the high power requirements of FPGA's.
- Kliment 12y agoNot only that, FPGAs can't do sensing, can't condition analog signals, can't drive large currents. The power consumption is just one of many limitations.
- programmer_dude 12y agoFPGAs could be one way of moving things into "software". IMO we need a revolution in "programmable" hardware before open hardware can really take off.
- asb 12y agoThis is actually one of the things we're looking at with the open-source lowRISC project. Moving aspects of the I/O system to RISC-V cores to enable you to implement SPI, I2C, I2S etc and other custom protocols in software. http://www.lowrisc.org/docs/memo-2014-001-tagged-memory-and-minion-cores/ http://www.lowrisc.org/docs/memo-2014-001-tagged-memory-and-... For integration of more analog components, I think the Silego GreenPak is a very interesting product http://www.silego.com/products/greenpak3.html http://www.silego.com/products/greenpak3.html.
- analog31 12y agoIn my view, this is being done continuously. Hardware designers are always conscious of what work can be moved to software. Thus the state of the art in hardware, at any given moment, will be exactly to do the stuff that isn't done well in software, or that is limiting the performance of software. For this reason I think hardware will always be hard, because we will keep moving the goalposts as technology advances. Interestingly, outside of the electronics realm, 3-d printing has begun to spur collaborative hardware design. So we should "never say never" about electronic hardware.
