September 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 -25°C to +70°C.
As well as low power benefits, the
MPC7455 offers 128-bit AltiVec™ 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® Discovery™ 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® Universe™ 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. |
