1–2 Chapter 1: About this MegaCore Function
Introduction
HyperTransport MegaCore Function User Guide © November 2009 Altera Corporation
Preliminary
Introduction
The HyperTransport MegaCore function implements high-speed packet transfers
between physical (PHY) and link-layer devices, and is fully compliant with the
HyperTransport I/O Link Specification, Revision 1.03. This MegaCore function allows
designers to interface to a wide range of HyperTransport™ technology (HT) enabled
devices quickly and easily, including network processors, coprocessors, video
chipsets, and ASICs.
Features
The HyperTransport MegaCore function has the following features:
8-bit fully integrated HT end-chain interface
Packet-based protocol
Dual unidirectional point-to-point links
Up to 16 Gigabits per second (Gbps) throughput (8 Gbps in each direction)
200, 300, and 400 MHz DDR links in Stratix and Stratix GX devices
200, 300, 400, and 500 MHz DDR links in Stratix II and Stratix II GX devices
Low-swing differential signaling with 100- differential impedance
Hardware verified with HyperTransport interfaces on multiple industry standard
processor and bridge devices
Fully parameterized MegaCore function allows flexible, easy configuration
Fully optimized for the Altera Stratix II, Stratix, Stratix GX, and Stratix II GX
device families
Application-side interface uses the Altera Atlantic
TM
interface standard
Manages HT flow control, optimizing performance and ease of use
Independent buffering for each HT virtual channel
Automatic handling of HT ordering rules
Stalling of one virtual channel does not delay other virtual channels (subject to
ordering rules)
Flexible parameterized buffer sizes, allowing customization depending on
system requirements
User interface has independent interfaces for the HT virtual channels, allowing
independent user logic design
Cyclic redundancy code (CRC) generation and checking to preserve data integrity
Integrated detection and response to common HT error conditions
CRC errors
End-chain errors
Fully integrated HT configuration space includes all required configuration space
registers and HT capabilities list registers
