Embedded applications span a huge range of sizes, from the very small devices to
which you refer, to quite complex devices. The cable settop boxes we develop have
over a hundred interrupt sources, typically run 250-300 threads, and have 192+
MiB of memory. For all that, we are very cost sensitive and are under constant
pressure to come up with reliable ways to save memory.
