PCIe Slave Device
When the Atlas 200 AI accelerator module is connected to a processor system and used as a PCIe slave device, users' AI service software running in the host system uses the PCIe channel to interact with the Atlas 200 AI accelerator module and offload AI tasks to the Ascend 310 chip.
In this application mode, you need to select a processor model that is compatible with the Atlas 200 AI accelerator module.
Processors compatible with the Atlas 200 AI accelerator module must meet the following requirements:
- Supports PCIe MSI-X interrupt (at least 116 MSI-X interrupts can be allocated).
- Supports three base address registers (BARs), and the sizes are 128 KB, 16 MB, and 64 MB respectively.
