The next generation of CompactPCI is beginning to roll out in the form of CompactPCI Express. This upgraded standard includes substantial performance increases, compatibility with both legacy products and the latest office PC technologies, and a unification of backplane buses into a single bus that supports both CPU-to-I/O and CPU-to-CPU communications. The first products based on this new standard, including those in the CompactPCI Express Product Guide that follows, are now beginning to appear, and represent the first look into this powerful architecture of the future.
