In addition, X100 further expands fusion computing instructions based on vector registers which can provide flexible and efficient matrix computing and other capabilities. Different from China’s ARM core, which only has access to Vector computing power and is severely limited due to Wassner protocol...
Extensions include atomic operations and support for AI and HPC-centric processing such as floating-point math (bfloat), matrix multiply, vector extensions, and quantization. Much of the initial negativity towards RISC-V was around unbridled customization and the danger this will lead to ...
Going back to March 2024, TechPowerUp and other Western hardware news outlets picked up on Alibaba's teasing of the Xuantie C930 SoC, and a related Xuantie 907 matrix processing unit. Fast-forward to the present day; Damo Academy has disclosed that initial shipments—of finalized C930 units—...
The advent of AI, AR/VR, computer vision, cryptography, and multimedia processing all require complex computation of large volume of matrix data. Unlike other vendor’s advanced SIMD, which has a narrow range of performance dictated by their architecture control, the RVV specification envisions a...
