System on chip and method for accessing device on bus
The present invention discloses a system on a chip and a method for accessing a device on a bus, and belongs to the electronics field. The system includes: a primary device, configured to send an access request; an extension module, configured to receive the access request sent by the primary device, and extend the ID signal in the access request according to the number of primary devices; a parsing module, configured to parse the access request output by the extension module to obtain an access response instruction; and a secondary device, configured to respond to the extended access request according to the access response instruction. By using the foregoing technical solution, the present invention allows the primary device to flexibly access the secondary device, thereby reducing requirements on the primary and secondary devices.
