Programming multi processor

[SPbeginner]

Hi

I'm new to Spresense.
Is there a way to use six processor at the same time?
Is there any sample code to refer?

Thank you,

Hi @spbeginner

Yes, it is possible to use 6 cores at the same time. Spresense uses ASMP for multicore.

You can see this example to see how it works:
https://github.com/sonydevworld/spresense/tree/master/examples/asmp

You can also see this example which uses ASMP and 6 cores at the same time:
https://github.com/sonydevworld/spresense/tree/master/examples/prime

Additionally, you can see an example that uses MPCOMM which is built on top of ASMP:

Hi @kamiltomaszewski
Does this mean that SMP is not supported?
Example seem present: sdk_tutorials_en.html#_feature_smp,
but it is unclear whether it works or not...
Thanks

Hi @mikhailz,

SMP is also supported. In fact, you can use SMP and ASMP at the same time. You can test how it works using examples/smp_asmp configuration.
