Ultra Low-Power 9D Sensor Fusion Implementation White Paper
This paper presents a case study on computing the 3D orientation of a device by means of a 9D fusion
algorithm. The focus is on optimizing the fusion algorithm for execution on the DesignWare® Sensor IP
Subsystem. Performance measurements show the benefits of using ARC® Processor EXtension (APEX)
accelerators, which improve both cycle count and energy consumption in comparison to other commercial
processors by a factor of 6-25.
