Now which direct pcie DMA to GPU from NVMe this is even more attractive. FPGA seems much more work than GPU.
My understanding is that FPGAs are targeted not because they are ideal for the task, but because they are commercially available. As in: the customers may rent a VM from a major cloud vendor with FPGAs attached.
Trying to grow a business that relies on bespoke hardware in the age of cloud monopoly is an uphill battle.
