Signal-allocator methods for allocating 1D arrays of data in device memory.
More...
Signal-allocator methods for allocating 1D arrays of data in device memory.
All allocators have size parameters to specify the size of the signal (1D array) being allocated.
The allocator methods return a pointer to the newly allocated memory of appropriate type. If device-memory allocation is not possible due to resource constaints the allocators return 0 (i.e. NULL pointer).
All signal allocators allocate memory aligned such that it is beneficial to the performance of the majority of the signal-processing primitives. It is no mandatory however to use these allocators. Any valid CUDA device-memory pointers can be passed to NPP primitives.
