[0022] Examples:
[0023] Examples of the invention figure 1 As shown, a control method of Nor Flash chip based on AXI bus is realized by the following system, which includes AXI bus interface 1, programmable device 2 and Nor Flash chip interface 3, AXI bus interface 1 and programmable device 2 The programmable device 2 is connected to the Nor Flash chip interface 3; the AXI bus interface 1 is connected to the SOC system, and the Nor Flash chip interface 3 is connected to the Nor Flash chip; the programmable device 2 is used to receive and process the information transmitted by the AXI bus. It is required to control the reading and writing of the Nor Flash chip to realize the communication between the AXI bus and Nor Flash. In the process of connecting the AXI bus and the Nor Flash chip, the programmable device 2 accepts the information sent by the SOC system through the AXI bus interface 1, and Decode the information content, and then output the decoded information content to t...
