In the figure, after a video image signal input from a certain pin of the four analog inputs AI11, AI12, AI21, and AI22 of SAA7111 is simulated, one channel can be output to the AOUT end through a buffer for monitoring, after A/D converter, A digital color signal and Brightness Signal are generated. After the Brightness Signal Processing and the color signal processing are performed respectively, the result of the Brightness Signal processing will be sent to the color signal proces

Ethernet data link layer actually contains the MAC (Media Access Control) Sub-layer and the LLC (Logical Link Control) Sub-layer. An Ethernet Card Mac chip not only needs to implement MAC Sub-layer and LLC sub-layer functions, but also provides a compliant PCI interface for data exchange with the host.
After Mac receives an IP packet (or a packet from other network layer protocols) from the PCI bus, it spl
