TDA4VH-Q1: If SafeRTOS is deployed on C7x of TDA4VH and MMU/MPU is enabled, will there still be performance degradation issues?

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH, TDA4VM

Tool/software:

After communicating with the SafeRTOS agent, it was found that using SafeRTOS on the C7x of TDA4VM and enabling MMU/MPU previously resulted in performance degradation. We would like to know if deploying SafeRTOS on the C7x of TDA4VH and enabling MMU/MPU will still cause performance degradation issues?

Hi,
Generally, enabling MMU/MPU with SafeRTOS can introduce minor performance overhead.
I will check with the SafeRTOS experts and get back to you.

Sivadeep.

Hi,

Are you experiencing the same performance degradation with FreeRTOS? Could you please check and confirm?

No performance degradation when enabling MMU/MPU with SafeRTOS.

Did you mean FreeRTOS?

Sorry for my mistake. No performance degradation when enabling MMU/MPU with FreeRTOS.

Hi,

If that's the case need to discuss with the safeRTOS owner for that.
