FPGAs differ from CPUs and GPUs in some ways. A significant difference
compared to CPU or GPU is generating a device binary for FPGA
hardware, which is a computationally intensive and time-consuming process.
It is normal for an FPGA compile to take several hours to complete. For
this reason, only ahead-of-time (or
) kernel compilation mode
is supported for FPGA. The long compile time for FPGA hardware makes
) compilation impractical.
Longer compile times are detrimental to developer productivity. The
Intel® oneAPI DPC++/C++ Compiler provides several mechanisms that enable
you to target FPGA and iterate quickly on your designs. By circumventing
the time-consuming process of full FPGA compilation wherever possible,
you can benefit from the faster compile times that you are familiar with
for CPU and GPU development.
