It is had each other when the difference on processing time, logical sequence or physical circuit being adjusted to cause to multichannel RGB synchronism switching modules 5
Delay, accumulates, delay is gradually increased, therefore need to cache half frame data again, afterwards multichannel RGB synchronism switchings module at any time
5 read simultaneously again, and according in RGB synchronous switching controls signal exchange to required passage, which forms the friendship of n × n
Matrix is changed, one-to-one can not only be exported, but also can a pair of of multi output.After multichannel RGB synchronism switchings module 5, each passage is defeated
It has been fully synchronized RGB data to go out.
The RGB data of each passage is respectively converted into after MIPI signals further according to MIPI by step 7), MIPI modular converters 6
Transmission synchronous control signal is sent to multichannel MIPI synchronous output modules 7 simultaneously.
The RGB data of input is carried out MIPI conversions to generate 8Lane all the way or two-way by the MIPI modular converters 6 of each passage
The MIPI signals of 4Lane, and it is synchronous by MIPI in the operations such as the reading in conversion, conversion, timing control, transmission state change
The MIPI transmission synchronous control signals that control module 1 is given carry out, the fully synchronized control of each operating procedure of each passage, and
And in physical circuit realization, the MIPI modular converters 6 of each passage are on same structure or BANK, during using same system
Clock works, and ensures that transfer process is fully synchronized.
Step 8), multichannel MIPI synchronous output modules 7 by MIPI signals be sent to respectively with each channel attached mould
