1354 OPs are for two double hashes.

SHA256(SHA256(Block_Header1)), SHA256(SHA256(Block_Header2))

so, 677 per double hash.

Although, there aren't completely full hashes, since the first and last few rounds (a few %) have optimized out.

Also, each ALU OP is a VLIW5 (very long instruction word) instruction which contains 5 integer operations that run simultaneously, so... depending on how you think about it,

could be ~3375 integer operations or 677 VLIW5 instructions

Hope this helps, let me know if you need any more help with this.  I am interested in how this turns out.
