1.0 Software Product Overview

Inter-Platform Communication Framework (IPCF) is a subsystem which enables applications, running on multiple homogenous or heterogenous processing cores, located on the same chip or different chips, running on different operating systems (AUTOSAR®, Linux®, FreeRTOS, Zephyr, etc.), to communicate over various transport interfaces (Shared Memory, etc.).

IPCF is designed for NXP embedded systems and features low-latency and tiny-footprint. It exposes a zero-copy API that can be directly used by customers for maximum performance, minimum overhead and low CPU load. The driver ensures freedom from interference between local and remote shared memory by executing all writing operations only in local memory domain. Customers can enforce memory protection for their software with XRDC/SMPU peripherals.

Customers can choose to build exactly what they need in terms of hardware (HW), operating system (OS) and transport interface.

1.1 Use cases

The following diagram illustrates some use cases addressed by IPCF.
