How does the chip BM1384 work?

Hi,

in order to build a miner software for my project, is it possible to tell me how the chip BM1384 works. Is it a SHA256 Hashing chip only? Is it a chip like video card ? how to send command to it? For example, how i send a a string for hashing and how to get the result?

Many thanks for your help
