We want run two processes in parallel (Something like multi-threading) on C7x DSP part of Jacinto 7. Is it possible?

If yes, please also share the documentation regarding this.

Tahir,

C7x supports multi tasking, you can refer to the following documentation to see how to create multiple tasks with FreeRTOS on C7x: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j721s2/09_00_00_02/exports/docs/pdk_j721s2_09_00_00_45/docs/userguide/j721s2/modules/freertos.html

Hello Varun.

Thank you for your reply.

Pardon my unlettered question, but I have two further questions:

1) RTOS will be running on either RF5 or Application processor? Only some tasks will be running on C7x? Is this correct? I mean is this C7x is capable of handling complete RTOS?

2) Parallel tasks will still be working based on time sharing basis? That mean although both of the tasks will be active at a time, but only one will be using the resources and hence to make them work in parallel, they will interrupt each other during this operation or duration of activity?

Please clarify both of these concerns.

Best regards

Tahir,

1. C7x runs a complete RTOS (FreeRTOS) & is capable of multi-tasking
2. This is correct
