MAY 24--Radstone Technology (Towcester, Northants, UK; www.radstone.co.uk), supplier of high-performance, rugged VME-based computer products, has developed its second-phase G4DSP signal-processor board that uses 7410 PowerPC RISC processors with AltiVec between 400 and 550 MHz. Essentially a processor and memory upgrade, the G4DSP provides each 7410 PowerPC compute node with 256-Mbyte SDRAM, 16-Mbyte FLASH, 2-Mbyte L2 CACHE, and an IBM-CPC710 64-bit/66-MHz PCI host bridge. The new board exercises the same crossbar-like PCI ring architecture and takes advantage of a PCI host bridge upgrade to take the processor bus and memory bus interfaces from 100 MHz to a peak of 133 MHz.
The G4DSP supports VxWorks/VxMP and VSPWorks DSP OS from Wind River Systems and also MPI message-passing libraries and VSIPL signal-processing libraries from MPI Software Technology. This is backed up by Radstone's Built-In-Test and driver support for PowerPC SBCs under VxWorks.
The G4DSP is available in five ruggedization build levels for industrial or extended temperature, shock, and vibration environments in either Air-Blown or Conduction-Cooled formats and with full software compatibility between build levels.
