1. Product Brief Figure.1 MLU270-X Series Intelligent Processing Card appearance Specially designed MLU270-X series dedicated to AI inferences and data center accelerations with high EER (Energy Efficiency Rate) The SIYUAN 270 ASIC has been designed based on several innovative technologies in the architecture of processors owned by Cambricon.
series can provide a great EER as high as 40 times of a normal CPU. There are embedded newly designed code/decode hardware for videos and pictures, so when the system have to handle this kind of tasks, MLU270-X series will decrease the load of CPU and the occupation for PCIe bandwidth, so as to increase the performances even more. Calculating flexibility and programmability SIYUAN 270 ASIC can provide supports to many kinds of Neural Networks.
