Tool/software:
Hi Team,
From the diagram below, it seems like the TCMs are shared between two cores each. Is this correct?
It seems like fro the sample codes that each core has its own TCM and other cores cannot access the TCM of different cores. Which is correct?
Best regards,
Mari Tsunoda
Hi Sreenivasa,
I will ask customer as to which sample code they are referring to.
In the datasheet, it lists the above. So does this mean that in dual-core each TCM is 64KB and they can access each other?
Is there an example in the SDK that you can point to that shows the TCM shared regions?
Best regards,
Mari

Please refer Figure 6-53 which shows the internals of the R5F dual core cluster.
1. Each core has its 32KB TCMA & 32KB TCMB (split in two interleaved banks of TCMB0 & TCMB1).
2. The cluster can operate in dual core mode i.e. both cores active and running either in SMP or AMP, or can run as in single core more with one R5F in the cluster disabled. In the single core mode (CPU0 active), the TCMs are still accessible to by CPU0) hence the total available TCM for the cluster (single core or dual core mode) is 32KB (TCMA CORE0) + 16KB (TCMB0 CORE0) + 16KB (TCMB1 CORE0) + 32KB (TCMA CORE1) + 16KB (TCMB0 CORE1) + 16KB (TCMB1 CORE1) == 128KB.
