					 --------



Software thread integration (STI) is a compiler technique which statically
interleaves instructions from functions of multiple threads into one while
reconciling control- and data-flow conflicts. This gives generic
microprocessors low- or no-penalty context switches, increasing
concurrency and enabling hardware to software migration on much slower
processors than previously possible.



This talk describes new methods that enable STI to tackle much more
challenging applications than previously possible. In particular,
interrupt response times are cut dramatically, long functions can be
integrated, and threads can now make asynchronous progress. We
demonstrate how these new methods are used on a network protocol
controller and a video display controller. The latter will be
demonstrated with working hardware designed around a 20 MHz 8-bit
microcontroller.
