Does anyone know of a compiler that translates a C++ code to MIPS Assembly Language

The two C++ compilers that matter support it:
GCC supports it, see here.
LLVM/Clang also supports it, see here.

The Intel compiler is only good if you compile for an intel architecture (AFAIK). The same goes for the IBM compiler, only good for IBM platforms (mostly super-computers and clusters). There are no other serious compilers besides those four (GCC, Clang, ICC, IBM).

I recommend you just check the imgtec site on developer tools.
