Board-level computer maker Thales Computers (Raleigh, No. Carolina) announces that it will now provide support for 2eSST (2-edge Synchronous Source Transfer) transfers on VME systems running under LynxOS. Thales Computers claims it's the first company to provide such board-level support.
The 2eSSTis bus protocol, introduced in 1997 by Arizona Digital as part of a proposed VME320 standard, provides VME-based systems with theoretical bandwidth of up to 320-Mbytes/s. That's versus 40-Mbytes/s for VME64.
The expanded bandwidth provided by 2eSST is billed as a significant element in Motorola's "VME Renaissance," an initiative to extend the capabilities of VME.
Thales now puts support for 2eSST into two of its software packages. One is dubbed the PowerLine LynxOS Board Support Package. BSP is for single board computers (SBCs).
The other package is called PowerLine LynxOS Multi-Node Package. It's for large PowerPC systems using SBCs and computing nodes.
Both PowerLine tools handle platform management requirements. The company claims using them can slash development time for complex VME systems, such as those designed into high-end signal processing applications.
"As more VME companies put 2eSST technology into their systems, software support becomes critical," notes Robert Morris, VP of Sales and Marketing for LynuxWorks.
"The performance of 2eSST VME---now an accepted VITA standard---and its support with realtime operating systems, eliminates costly dedicated mezzanine and fabric," points out Robert Negre, VP of Engineering for Thales. "This greatly improves time between failure (MTBF) figures, and lowers cost---two key things defense and aerospace system developers need."
Three Thales boards currently feature 2eSST. Products include the PowerNode3, a high-end computing node based on single and dual Motorola PowerPC G4 7457 microprocessors clocking at 1 GHz, and the PowerEngine7, an SBC based on single or dual IBM PowerPC 750FX processors. The V4G4c Computing Node packs four Motorola PowerPC 7410 (G4) processors with Motorola's AltiVec vector processing units.
For each board, an ALMA2e VME-PCI bridge designed by Thales Computers and manufactured by IBM France provides 2eSST capability. The two boards come in ruggedization levels from benign through mission-critical.
