Interconnection Structure(s)

The Sun Fireplane System Interconnect

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