An autonomous vehicle system runs two distinct processes on its onboard Linux computer. Process A constantly reads high-resolution LIDAR point clouds (generating gigabytes of data per second). Process B must analyze this data in real time to detect obstacles. The system architects require an IPC mechanism that minimizes CPU overhead by avoiding copying the data through the operating system kernel entirely.
Which IPC strategy is the most appropriate for transferring this data, and why?

Question

An autonomous vehicle system runs two distinct processes on its onboard Linux computer. Process A constantly reads high-resolution LIDAR point clouds (generating gigabytes of data per second). Process B must analyze this data in real time to detect obstacles. The system architects require an IPC mechanism that minimizes CPU overhead by avoiding copying the data through the operating system kernel entirely. 
 Which IPC strategy is the most appropriate for transferring this data, and why?

Answer

TCP Sockets , because they establish a persistent, reliable stream that guarantees no point-cloud data is lost or corrupted in transit between processes.

Answer

Signals , because they act as asynchronous hardware-level interrupts that can instantly pass the complex point cloud variables to Process B with zero latency.

Answer

POSIX Shared Memory , because it allows both processes to map the same physical memory pages into their own address spaces, enabling direct exchange of large amounts of information.

Answer

POSIX Shared Memory , because it provides built-in, automatic synchronization mechanisms that effectively manage the speed gap between the real-time producer and consumer.
