- Each thread executing this kernel computes one or more output's volume planes.

- the third thread [16,24] and the fourth thread [25,31].
-
- The algorithm outer loop iterates over Z, P, Y, X where P is the depth/3rd dimension of each kernel. This order is not arbitrary, the main benefit of this
- is that we setup the neon registers containing the kernel's values only once and then compute each XY using the preloaded registers as opposed as doing this for every XY value.
-
- The algorithm does not require allocating any additional memory amd computes the results directly in-place in two stages:
- 1) Convolve plane 0 with kernel 0 and initialize the corresponding output plane with these values.
- 2) Convolve the remaining planes and accumulate the results in the output's plane which has been initialized in step 1.
