If you want to continue tracing the source, Newton uses arm (Apple was an early investor in arm ). In addition, there are only a few gadgets mentioned above, and countless arm processors are running in embedded systems.
Arm is famous for its low power consumption and small size, and its performance is also outstanding in products with the same power consumption. This str

The card computer boom triggered by Raspberry Pi has also led to the development of small-sized card computers by embedded developers in China. The well-known embedded developer in China, tianyinao technology and Feiling embedded system, also developed card computers. Now, we will compare the basic parameters of the embedded E8 chip computer with the OK335xS-II Development Board of Feiling.
Comparison of basic parameters:

(4) TCP packet matching
TCP is also one of the most important protocols in the TCP/IP protocol stack. It provides end-to-end reliable data streams. at the same time, many application layer protocols use TCP as the underlying communication protocol, because TCP matching is very important.
If you want to match the HTTP communication data, you only need to specify a condition that matches port 80.
