Hybrid processor rips through signal
processing
The V4DSP FPGA/PowerPC processor combines dual Virtex-4 FPGA processing nodes together with a Freescale MPC7448 PowerPC processor operating at speeds up to 1.4GHz.
Reflecting the trend towards reconfigurable computing and providing a solution for applications demanding increasingly powerful front end signal processing, Radstone Embedded Computing has released the V4DSP FPGA/PowerPC processor Designed for the harsh environments typical of military and defence applications and featuring dual Virtex-4 FPGA processing nodes together with a Freescale MPC7448 PowerPC processor operating at speeds up to 1.4GHz, the V4DSP also provides support for Radstone's acclaimed Axis advanced multiprocessor integrated software environment, enabling the development of highly scalable multiprocessor systems

Ethernet switch meets US military requirements
Radstone Embedded Computing has released the CPX24 rugged managed Gigabit Ethernet switch.
"With this announcement, Radstone now has perhaps the industry's most advanced, most complete rugged signal processing solution", said Stuart Heptonstall, Product Marketing Manager at Radstone Embedded Computing.
"The V4DSP provides a powerful solution for front-end signal processing; the quad processor G4DSP family delivers outstanding performance in back-end signal processing; the StarSwitch StarFabric switch enables multiple V4DSPs and G4DSPs to be physically configured in highly scalable multiboard systems - and the Axis software environment substantially eases development of leading edge, multiprocessor solutions".
At the heart of the V4DSP are two of the latest Virtex-4 FX 60/100 FPGA nodes from Xilinx, together with a top-end MPC7448 PowerPC featuring the AltiVec general purpose processing node, which can be used as the first back-end application processing stage - potentially saving on chassis slot count.

Acquisition card eases access in tight spots
The ICS-8145 is the only data acquisition card currently available that combines rear I/O with onboard signal conditioning circuitry in a rugged single-slot package.
Speed and ease of development and deployment are enhanced by the provision of wide-ranging software support including a Radstone board support package to simplify user operations, and a comprehensive FPGA intellectual property (IP) wrapper called V-Wrap, which is Radstone's preprepared set of VHDL interfaces to the Virtex-4's embedded I/O and memory.
The V4DSP features two StarFabric ports at the P0 connector to enable multiboard connectivity, and a choice of mezzanine support: either a 64bit/66MHz PMC site can be configured, or an XMC site equipped with eight multigigabit transceivers to the two Virtex-4 nodes, each operating at up to 3.125GHz to yield exceptional mezzanine bandwidth.
Taking advantage of this bandwidth, the ICS-8550 ADC XMC module from ICS provides 210MHz per channel simultaneous sampling and uses an onboard Virtex-4 FX device for filtering and preprocessing.
"The combination of V4DSP and ICS-8550 gives an unrivalled front-end data acquisition and signal processing solution", noted Heptonstall.
