Hello sir,

I’m researching on Drive Thor SoC. and curious about the existence of physical DSP chip (conventional DSP chip like ADI, Cadence, etc.) So I searched on the web but I could not find concrete clue whether there exist DSP or not.

Some forum says it has dual HiFi5 (NVIDIA Jetson Thor: New SoC Features Guide | RidgeRun Developer Wiki) but it’s Jetson platform, not Drive platform.

I read the article that NVIDIA platform utilized ARM cortex cores as APE (Audio Processing Engine)

is Drive platform also uses ARM core as APE?

Dear @djlee8 ,
The available accelerators/engines are listed under Specifications at DRIVE AGX Autonomous Vehicle Development Platform | NVIDIA Developer

Audio is not supported on DRIVE AGX devkits.

May I know your use case details?

Could you please provide any update for this topic?

Hi @SivaRamaKrishnaNV and @carolyuu thanks for the feedback. the actual use-case details is automotive sound systems such as chimes, alerts, multi-media processing, voice ECNR, etc.

Although conventional historical architecture relies on DSP chips customarily, ARM architecture already had been expanding its capacity to support various signal processing. I think that’s why some previous NVIDA platforms utilized Arm core rather than dedicated DSP chip. QNX’s sound solution also provides this flexibility, scalability by enabling those use-cases to be ported on ARM cores with more standardized interface and dev environment. So I wondered NVIDA is also acknowledged this and skipping DSPs by replacing it with ARM cores to enable more scalable environment.

Dear @djlee8 ,
Yes. ARM cores are used for audio processing on DRIVE. But note that audio is not enabled on DevZone DRIVE OS release.
