For those who came in late Prple is the organisation set-up by Imagination Technologies to support open-source software on the MIPS architecture.
The big names follow CUPP Computing, Elliptic Technologies, Imperas Software, Kernkonzept and Seltech joined the foundation at lower levels.
In a statement the Foundation said that the newcomers to the prpl Foundation's board of directors will participate at the executive level and appoint representatives to the technical steering committee and to engineering groups including the security.
So in otherwords the key players will be advocating an open source approach to MIPS.
Prpl, is open to other architectures, and focusses on "datacenter-to-device portable software and virtualised architectures", it said. Initial domains onm its hit list are: datacenter, networking, storage, connected consumer, embedded and IoT.
