Multi-camera serial video data conversion for graphics processing unit (GPU) interface

Abstract:

Systems, methods, and apparatus for converting serial video data for a graphics processing unit (GPU) interface are disclosed. In one or more embodiments, a disclosed method comprises receiving, by each of a plurality of gigabit multimedia serial link (GMSL) conversion modules, n-bit length serial video data from a plurality of high-resolution cameras respectively. The method further comprises converting, by each of the GMSL conversion modules, the n-bit length serial video data to m-bit length serial GMSL video data, where n is equal to twice m. Also, the method comprises receiving, by a GMSL to camera series interface (CSI) conversion unit, the m-bit length serial GMSL video data from each of the GMSL conversion modules. Further, the method comprises converting, with the GMSL to CSI conversion unit, the m-bit length serial GMSL video data to m-bit length serial CSI video data, which is compatible with the GPU interface.
