Zynq from Xilinx uses an AXI bus between the CPU and logic. The first gen ones are not cache coherent between the logic and CPU but I believe UltraScale will be. I don't know much about PCIe, but how is AXI much lower latency?

There is a cache coherent FPGA-CPU DMA interface in Zynq-7000: the Accelerator Coherency Port (ACP).
