Since its release, there have been several revisions to the SPARC architecture. SPARC has introduced many new features in version 8, which includes multiply and divide functionality and a 128-bit quad-precision register.
In addition to Sun’s own Solaris, OpenSolaris and SunOS, SPARC is designed to support other OSs such as NetBSD, OpenBSD and Linux, among others.
