+ <h2>Abstract:</h2>
+ <blockquote>
+ Random access memory (RAM) is tightly-constrained in many 
+ embedded systems. This is especially true for the least expensive, lowest-power embedded systems, such as sensor network 
+ nodes and portable consumer electronics. The most widely-used sensor network nodes have only 4Ð10 KB of RAM and 
+ do not contain memory management units (MMUs). It is very 
+ difficult to implement increasingly complex applications under 
+ such tight memory constraints. Nonetheless, price and power 
+ consumption constraints make it unlikely that increases in RAM 
+ in these systems will keep pace with the requirements of applications.<p>
+ 
+ We propose the use of automated compile-time and run-time 
+ techniques to increase the amount of usable memory in MMU-less embedded systems. The proposed techniques do not in- 
+ crease hardware cost, and are designed to require few or no 
+ changes to existing applications. We have developed a fast compression algorithm well suited to this application, as well as run-time library routines and compiler transformations to control 
+ and optimize the automatic migration of application data between compressed and uncompressed memory regions. These 
+ techniques were experimentally evaluated on Crossbow TelosB 
+ sensor network nodes running a number of data collection and 
+ signal processing applications. The results indicate that available memory can be increased by up to 50% with less than 10% 
+ performance degradation for most benchmarks.
