GE Intelligent Solutions' G4DSP-XE (formerly by Radstone) incorporates four MPC7447 compute nodes to provide massive signal and data processing performance. At the heart of G4DSP-XE is its AccelerX™ loosely coupled PCI-X architecture enabling ultra-fast node-to-node communications. All other data paths including two PMC sites are independently bridged from the AccelerX ring so PCI-X speeds are maintained.

For fast interprocessor messaging, each compute node provides an interface into a central hardware message passing accelerator. This allows the fast execution of interprocessor mailbox interrupts and semaphores. Also provided is a common time base allowing messages and/or data buffers to be time-stamped; thus each G4DSP-XE in the system maintains the local time at the same value.

Multiboard scalability is greatly enhanced by the use of two StarFabric ports at P0. This can also be complimented by the use of StarFabric PMC, PMC-StarLite and the forthcoming StarCarry PMC carrier.

For accelerated software development G4DSP-XE provides four Gigabit Ethernet ports allowing simultaneous code development and debug on all four nodes. Software support includes LynxOS® real-time operating system, Radstone Message Passing Library and VSI/Pro VSIPL libraries with LynxOS.

G4DSP-XE is available in 4 ruggedization levels, enabling it to operate in industrial or extended temperature, shock and vibration environments. These environments range from Air-Blown 0ºC to +55ºC through to conduction-cooled -40°C to + 75°C.
