One other idea that may be of interest, though, is the concept
of "placing" a custom allocator and its associated pool at a known physical address and granting these the one-shot allocation character that you describe. I have used this technique in combination with various sets of microcontroller registers to overly STL containers like a vector on top of, say, the background readings from a hardware DMA. In this way the DMA "fills up" your vector in a CPU-independent fashion and the user can read the results from the underlying hardware layer---properly packed in the container---with essentially zero cost. I have not yet seen anyone else do this with the STL.
I assume this vector can't be resized. Why use a vector instead of for example an array or ptr pair? Olaf
Because I never figured out a way to *place* an array at the known physical address in memory where I want it, such as 0xFFE0, or whatever the address of, say, the ADC result registers may be in the microcontroller. Maybe there is a simpler way to do things like this. But I never got it. Any advice would be welcome. Best regards, Chris.
