The invention discloses an MIPI C-
PHY signal generating method, device and
system. The method comprises the following steps: 1) receiving a C-
PHY signal starting parameter and image
source data, and performing
data management and flow control according to the starting parameter; 2) packaging a code
stream in the starting parameter to form an LP
signal group packet; 3) performing one-hot encoding on the data of the LP signal group packet, mapping an encoded LP signal to a 3-wire for transmission; 4) packaging the image
source data, and distributing a packaged HS signal onto each lane; 5) encoding the HS signal, then outputting the encoded HS signal, and converting the parallel HS signal into a serial output of each wire; and 6)
aliasing a high speed signal and a
low speed signal to form a C-
PHY signal source, and outputting the C-PHY
signal source to a module. parallel 6lane is maximally supported, the
data transmission speed of 17.1 Gbps per lane meets the
throughput requirement of a C-
phy module of any resolution on the market, the adaptability is high, the
layout and wiring are simple, and the hardware cost is low, so that the MIPI C-PHY signal generating method, device and
system are worthy of popularization and application.
