Chen et al. [Che02] proposed software-controlled code compression for
Java. This method compresses read-only data, which includes virtual machine
binary code and Java class libraries. Read-only data is put in a scratch-pad mem-
ory on decompression. Compression allows some blocks in the on-chip memory
system to be turned off and others to be operated in low-power modes.
