Do you know how the programming languages you often use are implemented? Today, let’s talk about this question. Smart humans discovered that by combining simple switches, they could express complex boolean logic. Based on this, they built the CPU, which can only understand switches in a simple way, represented numerically as 0 and 1. The … Read more

RISC-V is also known as “the Linux of CPUs.” For some, this title feels like a legacy and an innovation at the same time, especially if you are a staunch believer in open source. However, I am a true pragmatist, and the excessive marketing of RISC-V has made me lose interest in the term. It … Read more

What’s the point of knowing all these details? This kind of thinking is actually… not wrong. Routers are quite similar to the computers or … Read more
This article is excerpted from “2022 Research Framework for Domestic Server CPUs“. In the post-Moore’s Law era, the performance benefits brought by the improvement of process technology are already very limited. The Dennard Scaling law constraints have led to a sharp increase in chip power consumption, and the cost of transistors has risen instead of … Read more
1. Overview With the surge of artificial intelligence and the widespread application of AI algorithms, deep learning has become a key focus of current AI research. In the field of autonomous driving, environmental perception, sensor fusion, and control decision-making all involve deep learning to some extent. The performance of autonomous driving is directly related to … Read more
In recent years, the concept of FPGA has become increasingly prevalent. For example, in Bitcoin mining, there are miners based on FPGA. Additionally, Microsoft previously stated that it would use FPGA to “replace” CPU in data centers, among other things. In fact, for professionals, FPGA is not unfamiliar; it has been widely used. However, most … Read more
