<p>Signal-allocator methods for allocating 1D arrays of data in device memory. </p>
<p>All allocators have size parameters to specify the size of the signal (1D array) being allocated.</p>
<p>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).</p>
<p>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. </p>
