This was already possible for the hard ip processors in the Xilinx FPGAs. For example through the user coprocessor interface of the ppc405 cores in some virtex-4 fpgas. So this patent is more of the same. Only the definition of the subject changed. Instead of an FPGA with cpu cores this is a processor with FPGA resources. FPGA fabric is slow compared to a Ryzen. So I expect that these instuctions extension option is only used for complex instuctions for specific work loads.
