Hi,
Is it possible to optimsise matlab generated code to use maximum capacity of nvidia drive. I am generating a script to create an around view image using the gsml cameras in nvidia drive. But, using matlab generated cuda code dosent seem to help. I am able to get the output, but there is a 5 second delay between the camera input and output. Is there any way to reduce this delay and increase the processing speed?
Thank You

Hi Abhijith,
Does the time (5 second delay between camera input and output) include the frame grab from the camera? For high-resolution images, the frame grab itself could be a source of the bottleneck. Is it possible to get the timing after frame grab?
Also consider turning on GPU Coder's Memory Manager through the GpuConfig.
cfg = coder.gpuConfig('dll');
cfg.GpuConfig.EnableMemoryManager = true;
See the link below for more details:
