The OpenPOWER Memory Bus (OPMB) Specification defines the OpenPOWER Memory Bus Architecture.
|
||
|
|
The architecture and specification are used to develop Memory Function Units (MFU) and
|
||
|
|
to integration of those MFUs into the OpenPOWER system structure.
|
||
|
|
An MFU is a logic block developed by a member of the OpenPOWER eco-system to attach special purpose memory technology and
|
||
|
|
function processing for data stored in the memory technology.
|
||
|
|
An example of MFU might be a database function accelerator which attaches dense flash memory technology.
|
||
|
|
|
||
|
|
This figure illustrates the concept.
