The resource cost when increasing the depth beyond the default value of 2 is similar to the resource cost of PIPOs. Namely each increment of 1 will require enough memory for a block, e.g., in the example above N * 32-bit words.

The stream of blocks object can be bound to a specific RAM type, by placing the BIND_STORAGE pragma where the stream-of-blocks is declared, for example in the top-level function. The stream of blocks uses 2-port BRAM (type=RAM_2P) by default.

Important: ARRAY_RESHAPE and ARRAY_PARTITION are not supported for stream-of-blocks.
