"Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4,"
"With our in-house silicon development, we're able to start our software development almost a year ahead of what we can do with supplier silicon,"
"Camera is the main workhorse of our sensor suite, generating the bulk of the data fed to the models," she said, "but the radar and lidar are critical to addressing the edge cases which would oth"
Rivian is building custom in-house silicon, including a 1600 sparse TOPS inference chip and a 5nm Rivian Autonomy Processor (RAP1) that integrates processing and memory on a multi-chip module. RAP1 will support the third-generation autonomy computer (ACM3), which can process 5 billion pixels per second. The third-gen autonomy hardware is planned for R2 vehicles in 2026. Lidar sensors will be added to future R2 models to supplement cameras and radar for improved edge-case handling. In-house silicon development enables starting software development roughly a year earlier than relying on supplier silicon.
