DSP board aims for leading edge imaging
Researchers at the University of Washington and IBM are using a DSP-based VME platform to help develop a practical technology for imaging the three-dimensional structure of individual molecules.
Upgraded VME board has more power and peripherals
Due to strong demand for the industry's first onboard, one-slot Fibre Channel VME board, Pentek now offers additional I/O, memory and real-time processing options.
The Model 9220 extends the processor baseboard's PMC connector into a second VMEbus slot where the three PMC modules can be mounted.
In addition, two VIM (Velocity Interface Mezzanine) modules can be mounted on the baseboard.
The capability of combining up to two VIM and three PMC modules simultaneously on a single baseboard gives the Model 9220 the I/O modularity and expandability unlike any other product in the industry.

Multiband receivers made for CompactPCI systems
Pentek has made its first foray into the cPCI market with 16- and 32-channel multiband-receiver boards featuring 14bit A/D convertors and Virtex-II FPGAs for signal processing.
The 9220 offers unprecedented modularity for both new and existing VME COTS systems for software radio, signal processing and data acquisition applications.
"The Model 9220 significantly broadens the range of I/O options for COTS system designers", says Rodger Hosking, Vice President of Pentek.
"Not only can our customers take full advantage of high-performance VIM modules, but now they can add up to three PMC modules for a wide array of miscellaneous I/O functions for system-specific interfaces".
"By choosing from thousands of off-the-shelf components, engineers can now create custom, two-slot sub-systems delivering tremendous performance, numerous high-speed internal interconnects and just the right I/O characteristics".
The Model 9220 architecture targets maximum connectivity, superior power management and support for a wide range of PMC modules.
All three PMC sites accommodate both 3.3 and 5V PMC modules with power being drawn directly from the VMEbus backplane, thus reducing power demands on the attached processor board.
The Model 9220 architecture features two 64bit PCIbuses, each capable of 33 or 66MHz speeds.
This multiple bus design offers the user a great deal of flexibility in both I/O configuration and bus speed.
PCIbus 1 offers a direct interface between the first PMC site and PCIbus 0.
This direct connection allows a 66MHz PMC module mounted in PMC site 1 to be mixed with slower modules while maintaining 66MHz operation.
Connectivity between the P4 connectors of PMC sites 1 and 2 is optionally available.
This allows communication between the PMC modules using P4 I/O, such as Pentek's 7131 A/D and digital receiver.
Pentek's VxWorks and TimeSys Linux board support packages provide software developers with a complete library of hardware initialisation, control and application functions for Pentek baseboards with the 9220 installed.
Pentek's ReadyFlow board support libraries offer an alternative to VxWorks and Linux, providing licence-free eCos development tools and pretested examples.
The Model 9220 initially supports the Pentek 4205 single G4 PowerPC MPC7457 I/O processor VME board with two programmable Xilinx Virtex-II FPGAs and the Model 4295 quad MPC7410 G4 PowerPC processor board.
Future support of the Model 9220 for the Texas Instruments C6203 is planned.
The Model 9220 is immediately available with 8-10 weeks ARO starting at US $995.
