This module transforms the data read from the memory into a format according to the LCD mod-
ule used. It has four different interfaces: the input interface, the output interface, the
configuration interface and the control interface.
The datapath can be characterized by two parameters: initial_latency and cycles_per_data. The
parameter initial_latency is defined as the number of LCDC Core Clock cycles until the first data
is available at the output of the datapath. The parameter cycles_per_data is the minimum num-
ber of LCDC Core clock cycles between two consecutive data at the output interface.
• The input interface connects the datapath with the DMA controller. It is a dual FIFO interface
• The output interface is a 24-bit data bus. The configuration of this interface depends on the

control signal is the data-request signal, used by the timing generation module to request
new data from the datapath.
