−The kernel runs in supervisor mode on the PowerPC, and performs the basic tasks of a microkernel. It is responsible for process isolation, memory management, and interrupt dispatching, as well as communication with [[IOSU]]. Cafe OS applications run as user mode processes, with separate address spaces and W^X memory protection. The kernel provides basic [[Cafe_OS_Kernel_Syscalls|syscalls]] for running processes.

The loader is responsible for loading RPL formatted libraries and executables into memory. It is a standard ELF executable named loader.elf. It includes a statically linked copy of zlib, probably for decompressing sections of RPL files.
