We aim to implement a fully homomorphic encryption algorithm using an FPGA accelerator in a way that eliminates the overhead produced by the device driver and memory format transitions. Fletcher is a framework that integrates FPGA accelerators with Apache Arrow, an in-memory format that reduces overhead when transferring data between platforms by creating tabular memory blocks.
Fletcher is programmed to function on top of IBM’s CAPI SNAP which eliminates the need for a device driver in an FPGA accelerator, reducing the overhead of exchanging data between FPGA and CPU and giving the FPGA coherent access to data in the main memory.
