Segment Prefetching

• Branch target prediction, should be similar to what we want to accomplish as opposed to branch prediction

IBM CBE Compilers (xlc/gcc)

• switches for automatic overlay generation

--auto-overlay=link.script outputs the generated overlay as a linker script and halts

• Using the GNU SPU linker for overlays
• Overlay manager source code
• Overlay manager source code, different comments
• Overlay manager source code, another version
• elf32-spu.c
