This paper discusses techniques for optimizing the architecture and power consumption of an automotive multimedia system based on Intel architecture. Uses of in-vehicle computing include route guidance, audio and video entertainment systems and communication for information and email. Integrating all of these functions into a single system can be challenging. In particular, designers face two important decisions, partitioning the system and reducing power consumption. This paper provides a discussion of an aftermarket system design and provides an example architecture with location of key components and interfaces. Once the system is partitioned, designers should focus on the many aspects of power management by exploring the hardware capabilities and the software techniques used to minimize power consumption without adversely affecting response time and processing performance.
