VAX vector architecture
Dileep Bhandarkar, Richard A. Brunner · ACM SIGARCH Computer Architecture News · 1990
The VAX Architecture has been extended to include an integrated, register-based vector processor. This extension allows both high-end and low-end implementations and can be supported with only small changes by VAX/VMS and VAX/ULTRIX operating systems. The extension is effectively exploited by the new vectorizing capabilities of VAX FORTRAN. Features of the VAX Vector Architecture and the design decisions which make it a consistent extension of the VAX Architecture are discussed.
