Also a tiny kernel design, the exokernel represents as little abstraction as possible, the complete opposite of the nanokernel. An exokernel is intended to give untrusted programs as much control over the hardware as possible, and in a secure way. This allows programs to take advantage of the details of present hardware instead of having to rely on the kernel to do this, which in some cases can result in drastic performance improvements. This goes however at the cost of having to write more complex software. This is quite often programmed in system libraries which provide the abstraction on the kernel's behalf. |
