Yusur (YUSUR Technology Co., Ltd.) focuses on the research and development of
special data processors.
The independently developed international leading DPU series products can be
widely used in ultra-low
latency network, big data processing, 5G edge computing, high-speed storage and
other scenarios,
helping computing power become the new productivity of the digital era.
The company put forward innovative Software Defined Accelerator technology and
independently
developed the chip architecture KPU(Kernel Processing Unit) and agile
heterogeneous Software stack
(HADOS) for domain-specific computing (DSA).
Now, adding the feature of obtain vdpa device's mac address automatically for
DPDK vDPA path.
