Spaghetti versus ISO 26262

Are You Ready for Tomorrow?

by Dick Selwood

There are times when you shouldn't really think too deeply about things. Last week I was driving along the motorway from London to Winchester. While accelerating to overtake, I saw the engine pass through 4,000 rpm, and I wondered about each piston moving from stationary at top dead centre to stationary at bottom dead centre and then back to top dead centre 50 times a second. (Geeky? Moi?) Sadly, I can't perform in my head the sum that would calculate the speed at which each piston was moving at its fastest, but it must be pretty speedy, and that cycle of movement would be putting all sorts of stresses on all sorts of metal parts. I eased my mental stress by consoling myself that, at least in my 15-year-old Golf, there wasn't software running on silicon to control the engine.

So I didn't have to worry that the software could be like that in the Toyotas that may have suffered unintended acceleration. There has been no resolution on whether the software caused the issue. The evidence of software guru Michael Barr was so damning that, while he couldn't say that the software caused the incident, he had the Toyota lawyers worried. Add to this the way in which the opposing legal team were being successful in throwing dust into the eyes of the jury and sowing doubt into their minds, and it is clear why Toyota settled out of court.  Read More

How about a series of low-end x86 chips for embedded systems? Would that fly?

Back in Ye Olden Tymes, AMD and Intel used to make a bunch of embedded x86 processors, but they both canceled them after a few years. That kind of burned a lot of embedded d…

I've done a couple server designs around Intel Xeon products, and while general documentation is easy to access with NDA, unless there are serious sales numbers behind the design, it's difficult to get additional support or docs.
