There are two modes:

  - system emulation (CPU + board and peripherals)
  - linux-user (CPU but with a Linux syscall interface)

If you are installing via your distros package manager you probably want
a package called qemu-user. You can build the only the user-mode
packages by issuing --disable-system to the configure script.

The closest thing to being a "pure" just the CPU is probably a
standalone usermode binary that uses semihosting calls rather than a
libc/syscall interface.
