At least Xilinx will be able to fall back to AMD’s amd64 or x86 architecture if NVIDIA will limit ARM core licensing. The new SoC products like ZynQ Ultrascale+ with ARM cores are really great.
- adrian_b 6y agoIt is really useful to include ARM cores in a FPGA, but Xilinx has remain stuck with completely obsolete cores (Cortex-A53 and Cortex-A72) since forever. The modern ARM cores, starting with Cortex-A55 (2017), use the corrected ISA ARMv8.2-A. On the ancient cores used by Xilinx, when writing multithreaded applications, it is annoying to lack atomic instructions. Yes, sure atomic instructions can be simulated with only the base ARMv8.0-A ISA, but it is not possible to guarantee worst case timings for the simulated atomics (because of retries).
