Most embedded software practitioners – sadly, not all – know that some form of what is normally called “Mutual Exclusion” is necessary when a read-write resource is shared among two or more concurrent activities, particularly (but not necessarily only) when test-and-set operations are involved. The expression “Mutual Exclusion” is so entrenched as a generic concept that I feel obliged to use it as such, but sometimes it is anything but mutual. Read more…
Horror of horrors! I, grateful as I am for having been properly educated in the nuances of my native language, have discovered a spelling mistake on my company’s website (which I composed myself). Unfortunately, I am currently estranged from my FTP password, so I will not be correcting this error until next Wednesday, 02/06/2010, at the earliest.
My company is offering a prize of £10 (that’s GBP 10) to the first person to discover this or any other spelling mistake, Read more…
Since Easter, when I promised a new release of this software, I’ve been exceptionally busy in a money-earning sort of way. I’ve noticed that others are blogging less now that their business has (presumably) picked up, so I’m not alone in disappointing my readers, but that is no excuse and so I have just uploaded the software I promised.

I like C++, but sometimes it appears to work with the aid of magic which I don’t fully understand. Last time (was it really 3 weeks ago?) I mentioned a problem I had with compiling the software I have been offering to subscribers to this blog with the GNU compiler. Or, to put it more honestly, I created a problem which g++ legitimately complained about, but which the other two compilers I tried (VC++ and IAR) allowed me to get away with. I am simplifying somewhat but basically I coded something like this: Read more…
The free software you may have downloaded from this site embodies an error of principle (details another time). It compiles with VC++ and IAR (ARM), and the code is correct and runs properly. However, I tried g++ today and it was less forgiving. Unfortunately, it’s right and I’m wrong, even though I got away with it up to now. I’m working on a fix and will post again when I have finished it.
The C++ dynamic memory software I published last week has been updated with a small but useful enhancement.

For the last couple of months, my software efforts have been diluted by the need to attend to other matters no less important but somewhat distracting. Now I have finally released some software. It is not the whole of SKC++, though. I learned so many things, at a detailed level (mainly about C++), in developing SKC++ that I realised that I had built “one to throw away”, as the saying goes. The refactoring is well underway and I have decided initially to release some of the essential elements of SKC++ in stages, as library modules which can be used more generally Read more…

Hypothesis: SKC++ doesn’t need semaphores. If you disagree with this, please comment, with supporting arguments. In the meantime, I’ll present a few arguments of my own, Read more…
