A filed patent by Intel has shed some light on the company's idea to somewhere, along the fuzzy lines of the future, introduce a Bitcoin mining hardware "accelerator" to the market. The application itself, for a "Bitcoin Mining Hardware Accelerator With Optimized Message Digest and Message Scheduler Datapath" was originally submitted in September 2016, so it's not exactly a novel idea. However, the fact that it has just now been published doesn't really mean there hasn't been work behind closed doors at Intel towards development of working silicon of this technology.

In the filing, it appears it's Intel's intent to create a chip that could augment the existing Bitcoin mining process by increasing energy efficiency. As they themselves put it, "Because the software and hardware utilized in Bitcoin mining uses brute force to repeatedly and endlessly perform SHA-256 functions, the process of Bitcoin mining can be very power-intensive and utilize large amounts of hardware space. The embodiments described herein optimize Bitcoin mining operations by reducing the space utilized and power consumed by Bitcoin mining hardware."

In the filing, Intel expects its bitcoin mining accelerator tech would he able to cut power usage by as much as 35%, and could be added to ASICs, SoCs, CPUs, and FPGAs as well. It's an interesting tech, really, and a needed one - the amount of energy bitcoin mining consumes is already overboard, and should see a much needed reduction.
