Tri-Cluster Deca-Core CPU Architecture?


#1

In the hardware documentation for the x20, it indicates it uses the Tri-Cluster Deca-Core CPU Architecture using

Dual-core ARM@Cortex-A72 MPCoreTM operating at up to 2.3GHz
Quad-core ARM@Cortex-A53 MPCoreTM operating at up to 1.85GHz
Quad-core ARM@Cortex-A53 MPCoreTM operating at up to 1.4GHz
Quad-core Mail T880, operating at up to 700MHz
Two ARM@Cortex-R4 processors operating at up to 800MHz for MD MCU

Are these acting independent of one another, or is this truly just a hardware “cluster” and the OS determines which set of cores takes on which workload ?

Also, if the OS handles the workload delegation, when is Linaro, ie Linux, going to be officially supported and/or has anyone attempted to build their own Linux images for use ?

Please excuse my ignorance, this is the first I’ve seen this “combined” architecture.

You are right about the Tri-Cluster Deca-Core CPU Architecture. It is means to these acting independent of one another and the OS determines which set of core takes on whitch workload. About the source code dowmload address, it’s as follow:
https://builds.96boards.org/releases/helio-x20/mediatek/aosp/16.10/
You can download the source code to build and burn the images.
