Abstract

Systems, methods, and devices are disclosed for synchronizing a map within shared memory for a navigating autonomous vehicle. A map, defined by a geographical area around an autonomous vehicle navigating a route, can be received and stored in shared memory. The shared memory can be a specific physical block of RAM. Concurrent access to the map within the shared memory can be granted to downstream nodes on the autonomous vehicle as the autonomous vehicle navigates the route. This shares the map among many nodes while, at the same time, allowing updates to the map without blocking those nodes at any time.
