These devices are designed to by used in conjunction with a single GPU (Graphical Processing Unit) or multiple GPUs. The GPU is left to handle tasks best suited for GPUs, but activities that can be performed more efficiently by an FPGA are offloaded.

 

The first known FPGA device of this nature is the Acorn. This is expected to be available for pre-order soon.

 

This page will articulate one or more reference implementations (e.g. Acorn + GTX 1080TI on a mining motherboard, low cost CPU, RAM, and Power Supply in an open air configuration). It's possible that multiple configurations will be identified.

 

This page will display the verified hash rate from the reference implementation for altcoins that have publicly available mining software support. The hash rate will be related to the current market price of the coin and ranked by profitability.

 

Acorn M.2 FPGA based GPU Accelerator

"The accelerator works by streaming high bandwidth hash state between GPUs and the FPGA over PCIe., allowing each piece of hardware to handle the portion of the algorithm it is best at. In general this means memory bandwidth or area heavy portions of the algorithm may be handled by the GPU, and hash algorithms designed for hardware implementations are handled by the FPGA. This approach works for any algorithm whose internal state is 256 bit (60Mh gains) or 512 bit (x16r, Lyra2Rev2, etc.) or smaller. The accelerator supports rapidly reconfiguring its algorithms from on-board DDR to enable handling of per-block or period (TimeTravel10) re-sequencing. It was designed originally to provide performance gains (especially for older GPUs with poor cores) and power savings for ETH by way of offloading the opening and closing Keccak calculations, as well as hash-selection to improve locality of reference for early ETH rounds. " - https://bitcointalk.org/index.php?topic=4391318.0
