VDI_D[32] maps to fgpi_start (fgpi_rec_start)
VDI_D[33] maps to fgpi_stop (fgpi_buf_start)
VDI_V2 maps to fgpi_d_valid
VDI_C2 maps to clock module fgpi_clk input
VDI_D[31:0] mapping depends on the VDI_MODE (Input Router) register settings as
described in the
This block contains all of the programmable registers used by the FGPI module
accessed through the MMIO bus. Refer to
descriptions. This block also handles clock domain crossing between the MMIO bus
clock and the FGPI module clock.
This block is used to pack incoming data samples into 32-bit words to be sent to main
memory. This module also informs the DMA Engine when a valid 32-bit data word is
ready to be loaded into the MTL DTL adapters FIFO via the DTL Initiators.
