Cluster related

Hi all,

I have a qustion about cluster. If freescale wants to introduce cluster in MSC8156, It's going to be seperated DSP and CPU clusters(control cluster) or cluster including both DSP and QUICC Engine Subsystem? Sorry if i am not supposed to post this question here.

best regards,

lpeng

Hello,
Could you please clarify what you mean by clustering?

The QUICC Engine only runs code related to parsing Ethernet / SPI data for the DSP cores.
Customers generally do not have access to this code.

Other CPUs can run whatever code a programmer puts on them.

Thanks you very much. My meaning is that cores may be organized into clusters as the number of cores increases.

I have another question: is there any CPU core that user can put code on in 8156?

Hi Ipeng,

A programmer may load code to either:

The local memory of one of the 6 core subsystems of the MSC8156,
or to shared memory.

The code is run by one of the 6 MSC8156 DSP cores.

If a user wants to use a general (non-DSP) core processing unit IN ADDITION to the DSP cores, and this is not for communications processing, then they would need to use an external device.

Ok, Thanks for your reply.
