In embedded systems,the core of a microcontroller (MCU) — the core (Core) determines the performance boundaries, power consumption characteristics, and software ecosystem of the entire platform. The current mainstream microcontroller architectures are represented by ARM and RISC-V, one being the cornerstone of the mature industrial sector, and the other being the pioneer of the open-source … Read more
Development and Usage of V85x E907 Core Author: @Yuzuki HD Original: https://bbs.aw-ol.com/topic/3017/ The V85x platform includes V853, V853s, V851s, and V851se. The suffix ‘s’ indicates that the chip has integrated DDR memory, while ‘e’ indicates that the chip has integrated ePHY. It features a Cortex-A7 core at 900MHz, RISC-V at 600MHz, and an NPU with … Read more
1.Concept of Embedded Systems An embedded computer is a dedicated computer system designed for specific applications, based on microprocessors, with customizable hardware and software to meet strict requirements for functionality, reliability, cost, size, and power consumption. In simple terms, an embedded system is software embedded into the Flash memory of application devices, specifically tailored for … Read more
Why Are Compilers So Critical? On resource-constrained embedded platforms, compilers are not only responsible for translating source code into machine instructions but also undertake multi-level optimization tasks: Code Optimization and Size Reduction: Through function inlining, loop unrolling, constant propagation, and link-time optimization (LTO), firmware performance is enhanced and size is minimized. Hardware-Related Parameter Configuration: By … Read more

This year, domestic large models have attracted global attention due to their low cost and high performance advantages of open source. Meanwhile, RISC-V (Reduced Instruction Set Computing) chips, based on open source architecture, are seizing new development opportunities with the explosion of AI. The industry believes that with the combination of “open source large models … Read more
Since the summer of 2010, the Berkeley research team has spent about four years designing and developing a complete new instruction set. This new instruction set is called RISC-V. From its official release in 2014, RISC-V has faced various doubts, but by 2017, the Indian government announced significant funding for RISC-V-based processor projects, making RISC-V … Read more
In the design of CPU cores, SIMD (Single Instruction Multiple Data) is a commonly used data parallel processing method that operates on multiple data elements simultaneously through a single instruction to enhance the computational efficiency and speed of the processor. SIMD has a wide range of applications, such as image processing, scientific computing, encryption and … Read more
May. Click the blue text to follow us 2025.05 In May 2010, Andrew Waterman, a student at the University of California, Berkeley, sent an email to his professors. After experimenting with various teaching methods for a three-month project, he concluded: They should revive the dying microprocessor architecture DEC Alpha. “I don’t see what new things … Read more
