Techniques for a pose component that may determine a pose are described herein. A pose may refer to the inertial pose or position of a vehicle which may be updated in real-time or near real-time. For example, the techniques may include receiving a plurality of input signals at a pose component and monitoring the plurality of input signals. The pose component may determine, based on the monitoring of the plurality of input signals, a particular pose update algorithm of a plurality of pose update algorithms for determining the pose and determine, using the particular pose update algorithm, the pose based the plurality of input signals and IMU measurements associated with a primary IMU.

Pose component

A field programmable gate array (FPGA) including a root of trust architecture. The architecture includes a system controller providing system control commands for the architecture and a cryptography processor for performing a hash or key operation for authentication of controller-embedded software and attestation of correct firmware in external system resources. The architecture also includes a lock-step fault-tolerant processor being responsive to messages from the system controller, and including a plurality of soft lock-step cores. Each soft core including separate memory and resources and operating on the same input, where each soft core provides output messages that are analyzed by a logic in the fault-tolerant processor that selects one of the messages to be output to the cryptography processor.
