There are lots of peripherals available thesedays, such as memory stick, CF
card, digital sensors, LCD, controller, etc. Usually the peripheral itself
is an embedded system and running software inside. I would like to know if I
can also call the inside software "device driver", cause these term is
already used by OS. I also want to know for the peripherals thesedays, do
they usually run an RTOS inside of themselves? Do they usually support
multi-tasking or just single process? I knew many years ago there were
usually no RTOS running inside of peripherals, typically only a piece of
software kept polling the device I/O ports. I understand they are all
different in nature, but I want to get a big picture.
