Many pervasive computing software technologies are targeted for 32-bit desktop platforms. However, there are innumerable 8, 16, and 32-bit microcontroller and microprocessor-based embedded systems that do not support the resource requirements of these technologies. We describe ongoing research that explores thefeasibility of creating a portable runtime-environment capable of executing across a wide-variety of 8, 16, and 32-bit processors and that offers mobile code and high-level language support. Our solution adapts a version of the language Forth called FCode and its environment to Jit these needs. We introduce the concept of a "jlit", a software construct similar to an applet but tailored to the needs of lower resource solutions to pervasive computing. We also describe work currently in progress.
