Vulcan is the outcome of this effort which involved adopting the [[ARM]] ISA instead of [[MIPS]] and enhancing the cores in various ways. Vulcan development started in early [[2012]] and has was expected to enter mass production in mid-[[2015]]. |
In [[2016]] [[Cavium]] acquired Vulcan from Broadcom which was introduced the following year. In early [[2018]], Vulcan-based microprocessor entered general availability under the {{cavium|ThunderX2}} brand. | In [[2016]] [[Cavium]] acquired Vulcan from Broadcom which was introduced the following year.
