JTAG has 10-pin, 14-pin, and 20-pin configurations. Although the number of pins and their arrangement differ, some pins are the same across these configurations. The definitions of each pin are as follows. 1. Pin Definitions Test Clock Input (TCK) —– Required 1 TCK is mandated in the IEEE1149.1 standard. TCK provides an independent, basic clock … Read more
FPGA (Field Programmable Gate Array) as a programmable logic device has been widely used in various digital system designs, and the JTAG interface is one of the most commonly used debugging/programming interfaces. Its quality directly affects the performance and reliability of the FPGA. Therefore, it is essential to diagnose and test the JTAG to prevent … Read more
Originally published on the WeChat public account “Embedded Fun”. During the process of FPGA development and learning, a key step is programming the board, making hardware “hard reality” is crucial. Generally speaking, using the JTAG interface is quite common, so many experts must have encountered issues where the JTAG interface malfunctioned or was damaged and … Read more
In embedded development and chip debugging, the JTAG interface allows developers to access the internal registers of chips through boundary scan technology, making it one of the important tools. However, when using the JTAG cable for program downloads, you may feel that the download speed is too slow. So how can we improve its speed? … Read more
Liver failure is a severe destruction of hepatocytes triggered by various pathological factors, leading to significant liver dysfunction. In clinical practice, it is often characterized by ascites, jaundice, hepatorenal syndrome, and infections, commonly associated with systemic inflammatory response syndrome. Its onset is rapid, the progression is swift, and it has many complications, making it extremely … Read more

The liver is one of the most important organs for maintaining life activities in the human body, being the largest digestive gland and the organ with the most active metabolism. It undertakes extremely important and complex functions, such as: synthesis and storage, bile secretion, detoxification, defense, and hematopoietic functions. The liver reserve function is an … Read more
The liver is one of the most metabolically active organs in the body and is crucial for maintaining the internal environment balance. Its main functions include the secretion of endogenous active substances and the transformation or clearance of toxic substances. When liver function is impaired due to factors such as viruses, drugs, or surgery, an … Read more
Early-stage liver failure refers to a state of disease where the patient’s liver function deteriorates sharply, posing a risk of liver failure but not yet meeting the diagnostic criteria for liver failure. Early warning of the risk of liver failure and timely intervention can help improve patient prognosis and reduce the economic burden on patients. … Read more
