Video Processor Module - Register Summary

32581C

7.3Register Descriptions

The register space for accessing and configuring the Video Processor is located in the Core Logic Chipset Register Space (F0-F5). The Chipset Register Space is accessed via the PCI interface using the PCI Type One Configuration Mechanism (see Section 6.3.1 "PCI Configuration Space and Access Methods" on page 173).

7.3.1Register Summary

The tables in this subsection summarize the registers of the Video Processor. Included in the tables are the regis- ter’s reset values and page references where the bit for- mats are found.
