The SpacemiT K1 is an octa-core 64-bit RISC-V AI CPU. Based on RISC-V open instruction set architecture, it is committed to creating a more energy efficient and more general AI processor platform, and promoting the construction of global open source and open ecological computing capacity. The K1 chip launched by Advance Space Time adopts an open strategy in design and ecology. Based on the general CPU, combined with a small amount of DSA customization (in line with the RISC-V IME extension framework) and a large number of micro-architecture innovations, the inclusive general CPU reuse the results of the open source ecosystem to the maximum extent, under the premise of compatible open source ecology, to provide TOPS-level AI computing power, accelerate edge AI applications. This means that K1 chips can avoid low-quality repetitive development and take full advantage of the richness and flexibility of open source resources for rapid deployment with small inputs.

Based on the AI technology route of advancing space-time, the K1 chip can support the deployment of a large number of open source models in a short time through the open software stack in the way of lightweight plug-ins. At present, the optimization deployment of about 150 models including image classification, image segmentation, target detection, speech recognition, natural language understanding and other scenarios has been verified. Open source model repositories such as timm, onnx modelzoo, ppl modelzoo and others have close to 100% support pass rates, and theoretically we can support all public onnx models.

As the first self-developed high-performance computing chip in advance space and time, K1 chip has made breakthrough achievements in AI, including memory performance, computing performance, floating point performance and other chip‘s three core performance, compared with ARM‘s Cortex-A55

SpacemiT K1 is mainly used for single board computer,network storage,cloud computer,smart robort,industrial control,edge computer,etc.
