Edge Computing: Key Technology in the 5G Era, Dominated by FPGA

Highlights: Detailed analysis of the impact of 5G edge computing on industrial structure. The demand for 5G computing power is driven by two main factors: signal processing and edge computing. On one hand, the increasing demand for communication signal processing imposes new requirements on computing power. On the other hand, 5G is the starting point … Read more

Launch of Domestic EtherCAT Solutions Competing with LAN9252

Launch of Domestic EtherCAT Solutions Competing with LAN9252

Currently, the EtherCAT slave solutions available on the market mainly include the following types. The traditional ones are chips like the Beckhoff ET1100, which require a master control + ESC + PHY, resulting in higher costs, making them unsuitable for the competitive pace of domestic general-purpose products. The second type integrates PHY with the ESC, … Read more

Who Moved My JTAG Port?

Who Moved My JTAG Port?

In the process of FPGA development and learning, a key step is downloading to the board. Achieving hardware “hard presence” is very important, and generally, the JTAG port is more commonly used. Therefore, I believe that some experts must have encountered issues with the JTAG port becoming unresponsive or damaged and unable to be used. … Read more

What Is JTAG? Understanding Its Basics and Applications

What Is JTAG? Understanding Its Basics and Applications

JTAG is an IEEE standard (1149.1) developed in the 1980s to address manufacturing issues in electronic boards. Today, it can be used for programming, debugging, and probing ports. But first, let’s look at JTAG’s original purpose: boundary testing. Boundary Testing This is a simple electronic board (also known as a “Printed Circuit Board” or “PCB”) … Read more
