This chapter describes the functional operation of the AlphaPC 164UX. The descrip-
tion introduces the Digital Semiconductor 21174 core logic chip and describes its
implementation with the 21164 microprocessor, its supporting memory, and I/O
devices. Figure 1–1 shows the AlphaPC 164UX major functional components.
Bus timing and protocol information found in other data sheets and reference docu-
mentation is not duplicated. See Appendix C for a list of supporting documents and
order numbers.
Note:
For detailed descriptions of bus transactions, chip logic, and operation,
refer to the 21164 Alpha Microprocessor Hardware Reference Manual
and the Digital Semiconductor 21174 Core Logic Chip Technical Refer-
ence Manual. For details of the PCI interface, refer to the PCI System
Design Guide.
