The MPL communicates with the System Layer, which is a platform-specific interface into the hardware and
software environment; this System Layer software must be implemented by the customer for his particular
environment. The software development kit includes shell functions to speed up the development of this
System Layer software. The MPL is independent of the Operating System (OS) since the System Layer
software handles OS-specific requirements.
The purpose of the DMP is to offload both timing requirements and processing requirements from the host
processor. Typically, raw data integration (sensor fusion) should be run at a high rate, often around 200Hz, in
order to provide accurate results with low latency. This is required even if the application updates at a much
lower rate; for example, a low power user interface may update as slowly as 5Hz, but the sensor fusion
should still run at 200Hz. The DMP can be used to minimize power, simplify timing and software architecture,
and saving valuable MIPS on the host processor for use in the application.
The IMU-3000 MPL Functional Specification describes in detail the API and System Layer routines needed
for interfacing to the IMU-3000.
InvenSense provides demonstration software in the form of source code and a compiled demonstration that
runs on a PC running Windows XP. This software works in conjunction with the hardware shown in the
figure at the top of Section 8. The PC demo software provides the functionality that allows a user to become
familiar with the use of gyros and accelerometers.
