Industry Weatherman Recently, at the Hong Kong Electronics Fair, it was discovered that the overall cost of AI glasses capable of taking photos is only around 200 yuan. This has caused a stir in the previously inflated market of pseudo-AI smart glasses, which were priced at over a thousand or two thousand yuan, especially those … Read more
Industry weatherman Currently, the mainstream AI glasses on the market are generally priced between 400 to 2000 RMB, with the main sales price range being 1000 to 1500 RMB. Qualcomm dominates the mid-to-high-end market with its mature AR/VR ecosystem, while domestic manufacturers such as Unisoc and Hengxuan are still seeking breakthroughs in low power consumption … Read more
1. Introduction to SoC Chips SoC (System on Chip) is a system-level chip that integrates modules such as CPU, GPU, RAM, NPU, and ISP, characterized by high performance, low power consumption, and high integration, widely used in smart devices. Compared to traditional MCUs, SoCs are more suitable for complex tasks (such as AI inference and … Read more
The Xilinx DMA/Bridge Subsystem for PCI Express (PCIE) IP (XDMA) significantly reduces the difficulty for FPGA developers in using the PCIE interface. By implementing a simple BD design, FPGA-side logic design can be achieved, and with open drivers and example code, developers can quickly establish end-to-end communication over PCIE.Currently, Xilinx has released drivers for XDMA … Read more
