Dream MCU wishlist item 732: Simple, high-speed serial protocol for fast memory mapped point-to-point IO.
Basically "PCIe lite". 8b/10b coded ~1 Gbps full duplex LVDS with packetized memory read/write requests bridged directly to AHB on the MCU side.
But no PnP enumeration, no device addressing, no request reordering, none of the other complexity of full PCIe. Something you can hang off a Cortex-M7 and use for interfacing to a lower end FPGA faster than QSPI.
