This is the GNU compiler for the emotion engine (mips r5900) chip. This is the main processing chip for the ps2. The compiler was nicely provided by snsys.com who probably would have preferred to keep in inhouse. However, the compiler is GPL'd so they had to release it.

There seems to be a couple of versions of this compiler online. The file iop-gcc-binutils.zip is the original from nsys.com. The file gnu-ee-binutils-gcc-1.0.tar.gz and gnu-ee-binutils-gcc-1.1.tar.gz have been patched to work under a linux environment.

Both Compilers are available from ps2.sourceforge.net
