| remoteproc/rpmsg | Upstream Linux kernel implementation, assumes Linux master, tight coupling between remoteproc/rpmsg. | Limited - rpmsg depends on remoteproc for platform-specific transport mechanism. | Linux, Binary FW (ELF) | TI/Wizery/Linaro | GPL-2.0 | ||
| OpenAMP remoteproc/rpmsg | Implementation of remoteproc/rpmsg on top of the OpenAMP libmetal framework. Focus on decoupling remoteproc/rpmsg, allowing non-Linux master cores. Interest in exploring rpmsg protocol implementation on alternative transport mechanisms (e.g. socket, UART, SPI, PCIe). | Limited - with plans to extend | Linux, Zephyr, FreeRTOS, Bare metal | https://drive.google.com/file/d/198kbwHojBHeM8QFnmSJd7dz5FLCpXPM9/view https://www.openampproject.org/ | Linaro/OpenAMP project (Xilinx, ST, Wind River) | Xilinx, ST, Wind River |

| rpmsg-lite | Lightweight RPMSG implementation targeting resource-constrained MCUs. Usable as transport layer for e.g. eRPC. MISRA C-2012 adherence, good basis for ISO26262 | Limited - transport mechanism implemented in platform-specific code. | Bare metal, FreeRTOS, QNX, ThreadX, Zephyr, XOS | NXP | BSD-3-Clause | ||
| IPCF | No updates in Linux SHM driver in 3-4 years | N | Linux, AUTOSAR, FreeRTOS, Zephyr, Bare metal | NXP | ?? | ||
