BlueField-3 IC
The NVIDIA BlueField-3 DPU integrates x8 / x16 Armv8.2+ A78 Hercules cores (64-bit) is
interconnected by a coherent mesh network, one DRAM controller, an RDMA intelligent
network adapter supporting up to 400Gb/s, an embedded PCIe switch with endpoint and
root complex functionality, and up to 32 lanes of PCIe Gen 5.0.
Protocol
Quad SPI NOR FLASH - includes 256Mbit for Firmware image.
UVPS EEPROM - includes 2Mbit.
FRU EEPROM - Stores the parameters and personality of the card. The EEPROM
capacity is 128Kbit. FRU I2C address is (0x50) and is accessible through the PCIe
SMBus.
