Hi,
I want to know what’s included in VDD_GPU_SOC-IN_POWER and VDD_CPU_CV-IN_POWER.

Is it correct?

  • GPU for VDD_GPU_SOC-IN_POWER
  • CPU and DLA for VDD_CPU_CV-IN_POWER.

I’m wondering what SOC refers in VDD_GPU_SOC

  1. As per the below figure in technical brief, SOC includes all of the CPU & GPU & ACCEL (ex. DLA, PVA).

  1. As per the below link, CV includes PVA and DLA
    NVIDIA Jetson Xavier - Evaluating Performance - RidgeRun Developer Connection

  2. As per the below link,
    The total power is close to the sum of GPU, CPU and 5V0.

Thanks in advance!

Hi @pz1004 ,
Actually, for Orin Core power design, there are four major power rails
1). VDD_CPU : For12-core Arm Cortex-A78AE v8.2 64-bit CPU.
2). VDD_GPU : For NVIDIA Ampere architecture with 2048 NVIDIA® CUDA® cores and 64 Tensor cores.
3). VDD_SOC : Logic rail for Orin SoC, excluding major sub-blocks such as CPU, GPU, and CV (Computer Vision)
4). VDD_CV : Power rail for Computer Vision cluster which consists of two primary engines: Programmable Vision Accelerator (PVA) and Deep Learning Accelerator (DLA).
