Interconnection Structure(s)
The Sun Fireplane System Interconnect
Features of the Sun Fireplane interconnect include:
- A fast operating frequency for greatly increased performance over previous designs
- High-performance crossbar switch design allowing simultaneous transfers between proces-
sors, memory, and the I/O subsystem
- Low latency memory access
- Completely separate address/control and data paths for flexible implementation
- Out-of-order transaction processing enabling multiple simultaneous transactions on the bus
- High-throughput paths to memory via 576-bit wide paths (including ECC)
- Economical implementation through distributed control (no central memory controller)
- Integrated support for multiprocessor configurations
