The Mercury Computer Systems MCPIO-DPRC is a PCI-to-RapidIO bridge module for 6U CompactPCI chassis, enabling high-performance data transfer between system components. It hosts two XMC mezzanine card sites with direct RapidIO connections to an 8-port crossbar ASIC, and supports multi-protocol adapters for inter-chassis I/O expansion.
Technical Specifications
• Form Factor: 6U CompactPCI
• Bridge Type: PCI-to-RapidIO
• Mezzanine Sites: Two XMC connectors for parallel RapidIO modules
• Crossbar Architecture: 8-port RapidIO ASIC
• Interconnect: Direct RapidIO fabric connection
• Chassis Access: Front and rear midplane connectivity
– Key Features
• Dual XMC sites enable parallel module deployment for increased I/O throughput
• 8-port crossbar ASIC provides dedicated RapidIO switching fabric
• PCI bus bridging integrates chassis resources with RapidIO fabric topology
• Multi-protocol adapter accommodation extends inter-chassis communication options
• Midplane design supports both front and rear panel access
– Typical Applications
The MCPIO-DPRC serves high-bandwidth imaging and signal processing systems that require deterministic, low-latency communication between processing boards and I/O subsystems. It is commonly deployed in real-time computing environments where RapidIO fabric interconnects provide superior throughput compared to traditional PCI-only architectures.
– Compatibility & Integration
Designed for integration with Mercury processing boards and CompactPCI system components. Accepts parallel RapidIO XMC modules and multi-protocol I/O adapters. Compatible with 6U CompactPCI chassis implementations that require unified PCI and RapidIO bridging.
