SBS Technologies announced at the 2003 Embedded Systems Conference the availability of the VG5 6U VMEbus single board computer (SBC), which features dual PowerPC processors to deliver the speed and bandwidth needed by performance-oriented applications such as real-time control, port video processing, and signal processing subsystems.

The SBC can be configured with Motorola's 800MHz to 1.3GHz MPC7455/57 PowerPC processors featuring AltiVed technology. The dual processor design allows two computing platforms with independent OSs to work in parallel within one slot.

Each processor also has its own memory and chipset, enabling one processor node to perform DPS tasks, while the other works as a general purpose CPU and facilitates the I/O functions on the board.

Each processor node also has an external 2MB L3 cache, up to 1GB DDR SDRAM with ECC, and a Marvell MV64360 chipset. The MV64360 provides two high-speed multi-protocol serial controllers supporting transfers up to 10 Mbps, one GbE port, one Fast Ethernet port, 2Mb of SRAM, up to 128MB soldered Flash memory, and four 32-bit timers.

Dual processor configurations support three independent onboard 64-bit PCI buses. One 64-bit/66MHz PCI-X bus is dedicated to communications between the two processor nodes; another is used exclusively for interfacing to a 64-bit/66MHz PMC slot. The third is used by the onboard VMEbus bridge and the 64-bit/33MHz PMC site.

Additional VG5 features include serial ATA interface, UARTs, user programmable FPGA for customized rear I/O, and optional PCI over P0 via PMC1. Optional rugged features are available for applications operating in harsh environments impacted by temperature, shock, vibration, humidity, dust, salt, or mist. Options for ruggedization include: extended temperature range of -40C to 85C, conduction cooling, conformal coating, stiffener bars, and wedge locks.
