TDA4VM: Accessing MMA accelerator on bare metal

Sainath R1

Part Number: TDA4VM

Hi,

1. So, is it possible to access MMA accelerator on bare-metal C7x core? If possible, please suggest a method.

2. If MMALIB is the only way then: Is it possible to compile/use MMALIB on bare-metal application (without TI-RTOS) on C7x core?

Thanks in advance.

Best Regards,

Sainath

PS) Kindly let me know, if the question is not clear.

Hi Sainath,

Please find answers as follows:

1. So, is it possible to access MMA accelerator on bare-metal C7x core? If possible, please suggest a method.

Anshu >>> YES, Refer current MMALIB test application, it is OS independent

2. If MMALIB is the only way then: Is it possible to compile/use MMALIB on bare-metal application (without TI-RTOS) on C7x core?

Anshu >>> MMLIB already have pre-compiled library which can be used in bare metal environment, so we don’t expect user for need to build it

What is your requirement, can you provide more context. We don’t expect customers to interact with low level library like MMALIB. The suggested interface for customers to work is at TIDL level, TIDL library is also bare metal (RTOS independent). So you can use it

Regards,

Anshu

Hi Anshu,

Thank you for the response.

Can you please provide the location of MMALIB test application. I am using PSDK RTOS version 06_03_00_106.

And one more query I have here:

Can we use IPC library on bare-metal C7x core (A72 (Linux) <-> C7x (bare-metal) ) ? If so, can you please provide the location/link for this kind of sample program if present.

What is your requirement, can you provide more context.

>> We want to use MMA accelerator for increasing the performance of multiplication operation in our application, which runs on C7x core. For this we want to integrate MMALIB in to our application and use its multiplication API's.

Thank you.

BestRegards,

Sainath
