Functional Description

This chapter describes the functional operation of the EB164. The description

introduces the Digital Semiconductor 21171 ASIC support chipset and

describes its implementation with the 21164 microprocessor, its supporting

memory, and I/O devices. Figure 1–1 shows the EB164 major functional

components.

Information, such as bus timing and protocol, found in other data sheets

and reference documentation is not duplicated. See Appendix C for a list of

supporting documents and order numbers.

Note

For detailed descriptions of bus transactions, chipset logic, and

operation, refer to the Alpha 21164 Microprocessor Hardware Reference

Manual and the DECchip 21171 Core Logic Chipset Technical Reference

Manual.

For details of the PCI interface, refer to the PCI System Design Guide.
