Transfer Time Reduction of Data Transfers between CPU and GPU

Transfer Time Reduction of Data Transfers between CPU and GPU

In real-time video processing data transfer between CPU and GPU is a time critical action; time spent transferring data is processing time lost. Several variants of standard transfer methods were developed and evaluated on nine computers and two smart decision algorithms was designed to help choose...
