[테슬라 FSD] TESLA FSD (Full Self-Driving Compute) 1/2

@ What is FSD?

• FSD (Full self-driving) is the world’s first purpose-built computer for autonomous driving
• SoC (System on Chip) that integrated CPUs, ISP, GPU, and Neural network accelerators
• Processing up to 2300 fps / 72 TOPs for neural network inference / 40W per chip
• Tesla’s FSD computer was designed to be retrofitted into any Tesla vehicle made since October 2016
• Two instances of the FSD chip

      - boot independently and run independent operating systems
      - independent power supply and sensor for safety
  

   

   

 

@ FSD charateristic

• 14-nm FinFet technology by Samsung
• 37.5mm x 37.5mm Flip Chip BGA package
• AEC-Q100 Grade2
• Two Neural network accelerator (NNA)
•  
  A72 CPUs, G71 GPU, ISPs for the rest of the system
•  
  Unmarked area : peripherals, NoC fabrics and Memory interface

@ into FSD

 

※ Simple process of inference

① Pre-processed input frames@ ISP

② frames stored in  DRAM

③ CPU instruct the NNA for image processing

④ NNA control data and parameter streaming into SRAM

⑤ NNA results streaming back to DRAM

⑥ NNA trigger and interrupt back to CPU complex
