The VME V2G4c and V4G4c computing nodes feature two or four 500 MHz Motorola PowerPC 7410 (G4) processors, respectively, with AltiVec vector processing units. The board also provides a 33% improvement in local bus speed, to 133 MHz. The on-board PowerPC processors utilize massively shared memory architecture to access up to 1 GB SDRAM memory in real time with extremely low latency. These boards are ideal for demanding applications requiring high-performance real-time data and signal processing, including sonar, radar, medical imaging and machine vision systems.
The VxG4c features include:
· Two or four 500 MHz Motorola PowerPC 7410 (G4) processors with AltiVec vector processing units
· 10/100BASE-T Ethernet port routed to the front panel or the P2 connector
· 64 KB L1 and 2 MB L2 cache for each processor
· Two PCI/PMC slots with an Avignon crossbar
· External I/O support
· 38W power consumption (V2G4c), 50W power consumption (V4G4c)
· PCI 32 support for VME 2eSST operation through Alma2e
· Supports VxWorks and LynxOS
· Available in all ruggedization levels
