In the previous article, we introduced CPUs and GPUs. Today, I will continue to introduce two other main players in the field of computing chips – ASIC and FPGA. █ ASIC (Application Specific Integrated Circuit) As mentioned earlier, GPUs have strong parallel computing capabilities, but they also have drawbacks, such as high power consumption, large … Read more
1 Before discussing FPGA, let’s pose a question. What is the essence of a chip? In my opinion, the essence of a chip is the circuit! Simply put, digital chips, no matter how complex, are fundamentally combinations of AND, OR, and NOT. This is one of the simplest chips available on certain platforms, the 74LS … Read more

Welcome FPGA engineers to join the official WeChat technical group. Clickthe blue textto follow us at FPGA Home – the best and largest pure FPGA engineer community in China. FPGA is a programmable chip, thus the design methods for FPGA include both hardware and software design. Hardware includes FPGA chip circuits, memory, input/output interface circuits, … Read more
In recent years, the concept of FPGA has become increasingly prevalent. For example, Bitcoin mining has seen the use of FPGA-based mining machines. Additionally, Microsoft previously announced its intention to use FPGAs in data centers as a “replacement” for CPUs, among other applications. For professionals, FPGAs are not a foreign concept, as they have been … Read more
Today, I want to share a board that is an industrial-grade core board developed by Chuanglong Technology, based on the Rockchip RK3588J/RK3588 + Unisoc Titan-2 PG2T390H FPGA design. It is a heterogeneous multi-core domestic platform. After reviewing the specifications of this product, I found that both the software and hardware parts are excellent, and its … Read more
Frequent product issues lead to testers working overtime, while developers are busy putting out fires. Is there a better solution?How can we continuously ensure the reliability and stability of products during rapid iterations? Embedded systems are generally the core unit of a product. The reliability of the embedded system determines the overall quality of the … Read more
Question 1: What is embedded systems? Various devices around us: Dormitory access control, mobile phones, electronic alarms (non-mechanical alarms), smart wristbands, cafeteria card machines, washing machines, rice cookers, air conditioners, balancing cars, quadcopters, routers, robots, etc., all belong to embedded devices. Definition: IEEE (Institute of Electrical and Electronics Engineers) defines it as a device used … Read more
