In some cases you can achieve small static code sizes by using dynamic
compilation and having a large dynamic code size. For embedded
controllers, this probably won't work.

The last paper basically says ``you can code infrequently-used things
compactly, frequently-used things non-compactly, and achive significant
space reduction with only minor performance loss.''


Please summarize other things you find.
