9.1 Video/Data Input Router
VIP and QVCP share a set of pins with two general purpose interface modules, FGPI
and FGPO (respectively). The input and output data routers allocate a different
amount of pins between these four modules. The allocation depends on the operating
mode of each module. The following sections describe the different modes of the
input and output routers.
These inputs can provide combinations of the following functions:
The VDI pins consist of 38 pins, split into 32 data pins, 2 clock pins and 2 valid signals
that indicate whether data is valid on the respective clocks.
The operating modes of the video/data input router are set by the VDI_MODE MMIO
register. A subset of the operating modes are presented in
656 digital video source with streaming data inputs. A complete behavior of the
output router is available in
