Overview
This chapter provides an overview of the Intel^® EP80579 Integrated Processor product
line architecture. Section 2.1.1, “Block Summary” gives a high-level summary for each
of the major blocks and their internal interfaces. Section 2.1.2, “External Interfaces”
reviews the EP80579’s external chip interfaces.
The block diagrams in Figure 2-1 and Figure 2-1 show the major EP80579 blocks.
Block Summary
• The EP80579 IA-32 core runs at 600, 1066, and 1200 MHz with an internal 400 or
533 MHz front-side bus (FSB) interface. The IA-32 core features a 256 Kilobyte 2-
way level 2 cache (L2).
• The EP80579 IMCH provides the main path to memory for the IA-32 core and all
peripherals that perform coherent I/O (e.g. PCI Express*, the IICH to coherent
memory). The IMCH includes the four channel DMA engine as well as a PCI
Express* root complex with 1x8, 2x4, or 2x1 interfaces. The memory controller
operates at 200-266-333-400 MHz, depending on external DDR and SKU
configuration. Depending on SKU, the EP80579 supports a single channel, 64-bit
with ECC, memory controller for external DDR-2 memory (400, 533, 667, and 800
MHz). The EP80579 also supports a 32-bit with ECC mode for cost-sensitive
applications.
• The EP80579 IICH provides a set of PC platform-compatible I/O devices that
include two SATA1.0/2.0, one USB1.1/2.0 host controller supporting two USB
ports, and two serial 16550 compatible UART interfaces. The IICH complex
interfaces to the MCH through the “NSI” internal bus interface.
• The EP80579 Acceleration and I/O Complex (AIOC) supports three Gigabit
Ethernet media access controllers, MDIO, Local Expansion Bus (LEB), two
Controller Area Network (CAN) interfaces, IEEE1588 (2-GbE and 2-CAN ports), and
SSP. In addition some SKU have three high-speed serial TDM interfaces that
provide up to 12 T1/E1. ASU and SSU provide the high performance packet
processing and accelerate common security capability.
