Peripheral NPU[edit | edit source]
The Neural Processign Unit (NPU) available on ORCA is based on iMX8MPlus SoC.
Description[edit | edit source]
The Neural Processing Unit (NPU) core accelerates vision image processing functions and provides enhanced performance for real-time use cases with hardware support for the OpenVX API.
Key features of the NPU block include:
- OpenVX 1.2 compliance, including extensions
- Convolutional Neural Network acceleration
- IEEE 32-bit floating-point pipeline in PPU shaders.
- Ultra-threaded parallel processing unit
- Low bandwidth at both high and low data rates
- Low CPU loading
- MMU functionality supported
- Performance Counters for DMA Profiling
- Data transfers between Neural Network Engines and the Parallel Processing Unit, with SRAM as local storage
- Neural Network Engine and Parallel Processing Unit synchronization with hardware semaphore
