HyperTransport™ System Architecture provides a comprehensive, technical guide to HyperTransport technology. It opens with an overview of HT systems, highlighting the technology's fundamental principles, basic architecture, and its many advantages. The book goes on to detail all facets of HyperTransport systems, including the protocol, I/O, routing, configuration, and more. It also features important performance considerations and addresses critical compatibility issues.
Essential topics covered include:
- Signal groups
- Packet protocol, covering control and data packets
- HT flow control, and how it differs from PCI flow control
- I/O ordering rules, including upstream, downstream, and host ordering requirements
- Interrupts, error detection, and error handling
- HT system management
- Routing packets, covering point-to-point topology and HT's fairness algorithm
- Device configuration
- The electrical environment, including power requirements and signaling characteristics
- HyperTransport bridges
- Double-hosted chains
- Anticipated networking extensions
- PCI, PCI-X, AGP, and X86 compatibility issues
