| Summary: | 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 the fastest method for each occasion. Results showed that the standard transfer methods can be beaten; by using the designed decision algorithms, transfer times between CPU and GPU (both ways) can be reduced by a factor of 7 compared to always using the standard methods. |
