Concurrent Technologies Rolls Out VP 742/20x PowerPC Based VME64x SBC

9/14/2004 - Concurrent Technologies has broadened its PowerPC based VME64x product range with the introduction of the VP 742/20x. This single slot board is designed around the Motorola® MPC7455 PowerPC® "G4" processor with speed options of 800 MHz or 1 GHz and up to 1.25 Gbytes 266MHz DDR SDRAM (with ECC). The VP 742/20x is designed to meet the explicit needs of high-end performance processing in the VME real-time single board computer market and includes onboard I/O interfaces for a PMC site, Ultra-160 SCSI, dual Gigabit Ethernet, graphics, keyboard and mouse. Vertical markets include military, aerospace, scientific and telecommunications industries. For harsher applications the 800MHz VP 742/201-E operates at -25C to +70C.

As well as low power benefits, the MPC7455 offers 128-bit AltiVecTM technology plus 64Kbytes L1 cache and 256Kbytes L2 cache. The 2 Mbytes of "backside" L3 cache assist processing performance. L1 cache locking enables specific key performance algorithms or code and an increased number of block address translation registers enables efficient embedded operating systems to support high-speed mapping of additional large data blocks. The MPC7455 processor connects to the Marvell® DiscoveryTM II (MV64360) PCI bridge, chosen for its flexibility and excellent performance characteristics. The MV64360 also provides dual Gigabit Ethernet channels, two PCI busses, 2 Mbytes NVSRAM and connects to 64 Mbytes of application Flash EPROM. The dual Gigabit Ethernet channels are independent of the PCI busses.

The VP 742/20x supports a 64-bit 66MHz PMC site with front panel I/O (rear I/O via optional P0) and features a USB port, two asynchronous/synchronous RS232/RS422/RS485 serial ports, four 32-bit general-purpose timers, a 32-bit CPU decrementer and 64-bit CPU time base, real-time calendar clock and the Tundra® UniverseTM II VME interface. An optional P2 or P2/P0 breakout is available.

Options are available for conformal coating and extended temperature versions.

The VP 742/20x will support a range of operating systems; it currently supports VxWorks®, Linux® and LynxOS®. Remote booting over the Ethernet is also supported.
