VMETRO announced the Phoenix VPF2, a rugged COTS DSP processing card, which integrates a Freescale MPC8641D processor, two Xilinx Virtex-5 FPGAs and a VXS based high-speed serial interconnect fabric.

The VPF2 tackles both high-bandwidth pre-processing and sophisticated back-end processing in one 6U VME64/VITA 41 product for demanding DSP applications, such as real-time video processing, surveillance, radar and other applications that demand the highest levels of flexibility and performance.

The processing heart of the Phoenix VPF2 is a Freescale MPC8641D dual-core processor based on Power Architecture technology. The cores run up to 1.25GHz with 2Gbytes of memory to support operating systems such as VxWorks and Linux. Integrated within the MPC8641D processor is a complete I/O subsystem, including two GbE ports, serial I/O, dual DDR/DDR2 memory controllers, VME interface and independent x8 PCIe links to the Xilinx FPGAs and the XMC/PMC site. The VPF2 has Ethernet options, which support both RJ45 and optical interfaces or backplane I/O.

Closely coupled to the MPC8641D processor are two Xilinx Virtex-5 SX95T FPGAs, optimized for DSP performance, or LX110T FPGAs, optimized for high-performance logic. With their on-chip serial transceivers, the Virtex-5 FPGA options provide high bandwidth off-board serial communications channels to processing and I/O sub-systems. Since the FPGAs connect to fast I/O streams, they can pre-process incoming data in real-time without bottlenecks. The Virtex-5 FPGAs perform pixel-rate computation, digital down conversion, FFTs, filters and encryption. The FPGAs are fully user programmable and can be configured from flash memory.

VMETRO speeds up the development time by providing TransComm, a data streaming communications toolkit. This toolkit simplifies connecting VPF2 FPGA centric systems together allowing the user to focus on key IP core development. Both FPGA devices are supported with 4x 4M x 18-bit banks of QDR SRAM and 2x 64M x 16-bit SDRAM. These memories allow large data sets, such as frame buffers or large FFT information, to be stored locally for maximum FPGA performance.

As with all members of VMETRO's Phoenix family, the VPF2 will be available in several environmental build options ranging from air-cooled commercial to rugged conduction-cooled.

The VPF2 will ship to customers in Q4.
