TimeSys is shipping a real-time Linux development kit for a PowerPC-based Motorola VMEbus board said to septuple throughput compared to other VMEbus boards. The TimeStorm LDK (Linux development kit) for the MVME6100 board includes a 2.6-series Linux kernel with advanced real-time capabilities, and the Eclipse-based TimeStorm LDS (Linux development suite). It targets aerospace, industrial automation, and medical imaging.

TimeSys says Motorola's MVME6100 is the first product to use the Tundra Tsi148 VMEbus-to-PCI-X bridge interface chip, said to enable transfer rates of 300MB/s on the VMEbus (40MB/s is the typical rate for VME64) while preserving compatibility with previous gneerations of VMEbus products.

Additional features of the board include:

  • Motorola MPC7457 1.267 GHz PowerPC processor with the 128-bit AltiVec coprocessor for vector processing
  • Tsi148 PCI-X bus to VMEbus bridge with 2eSST protocol for 320MB/s transfer rate across standard VMEbus
  • Up to 1GB DDR ECC memory
  • Two 64-bit PCI-X bus interfaces, one dedicated to 100 MHz PMC-X support and the other to the VMEbus bridge at 133 MHz
  • Dual 64-bit, 33/66/100 MHz PMC-X expansion slot support
  • Dual Gigabit Ethernet interfaces

TimeSys lists the following features for its MVME6100 LDK:

  • 2.6 Linux distribution optimized for the MVME6100
  • Integrated real-time capabilities such as schedulable hard and soft interrupt handlers, priority inheritance mutexes, and a fully preemptible kernel
  • Support for all external buses and interfaces, including kernel drivers for all on-board devices
  • Royalty-free, high-power runtime for commercial deployment
  • GNU toolchains to facilitate development and debugging of custom applications
  • Graphical Eclipse-based TimeStorm Linux Development Suite for Linux application development on Windows or Linux hosts

TimeSys CEO Larry Weidman said, “We are pleased that Motorola, a leader in embedded computing, has selected TimeSys to deliver the Linux Development Kit for its most advanced VMEbus single board computer. Motorola felt that having a robust, cost effective and commercially available Linux solution for the MVME6100 was important, which highlights the increasing adoption of Linux as the platform of choice in even the most demanding applications.”
