Good example of evolution at work. Improvements in one place, i.e. multicore chips, lead to improvements in others like powertrains.
I thought this required changes in compiler design to take advantage of multicore chips. Perhaps that was in the cae of parallel programming. I am not sure that applies here but perhaps someone could speak up on that.
I would also expect the multicore design to be extended to additional cores just like our workstations are now quad core, hexcore or even octo core designs. I think this saves power on the chip as well since the multicores reduce the need for higher clock speeds.
Compilers have been/are being updated to support multicore for the appropriate platforms.
However, multicore processors may be used without the hard requirement for a multicore-aware compiler. It depends on the actual chip architecture, as well as the software application design and partitioning.
Can anyone explain this to me? In 1972 I bought a new Dodge Colt 1600, made by Mitsubishi. It could seat 4 normal sized adults, regularly got 40+ miles to the gallon and had enough get up that I got a ticket for doing 77 in a 60 mph zone. (I was younger then, so cut me some slack.) It had a 2bbl carb and coil ignition so I imagine the exact same vehicle would perform better today with fuel injection and electronic ignition. The car cost about $2200 as I recall and the only extraordinary maintenance I had was to replace the differential at about 55 thousand miles.
For some reason other cars liked to run into it while parked, sitting at a stop sign or just drivng normally. After the 4th such occurance we got rid of it. My question: how is it that a car like that could be built in the early 70's, without onboard computers, 40-70 pounds of wire, etc. Are we not smarter today? I'm just asking.
Ah, complication equals profit when these many units start dying.
And making a car engine in service that gets 7% of it's fuels energy to move it to 8% for all that cost is just not smart. Far better go directly to EV drive with it's 20-65% eff depending on the power source.
The only eff way to use an ICE is running at constant speed driving an alternator which doesn't require complicated junk to be eff, cleanish as an ICE can be. The Lotus EV Range Extender is an example of the future ICE in vehicles.
Far cheaper is lighter unibodies, better aero and even chopping off a wheel you get into the 100mpg and up class. Even the smaller SUV's could do this if they wanted to.
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
