One example is a PowerPC family of CPU boards that is fast enough (up to 800 MHz, increasing to 1.2 GHz in 2004) for real-time applications, yet does not need many fans to cool the CPU (6W as compared to 30W-90W for a state-of-the-art Intel CPU--quite a difference.) PowerPC-based VMEbus
CPU boards of the IBM 750 FX/750 GX family are also significantly faster than PowerPC microcontrollers, available with up to 300 MHz (increasing to 550 MHz in 2004).
-- Tsi148 PCI-X bus to VMEbus
bridge with 2eSST protocol for 320MB/s transfer rate across standard VMEbus
The prime objective of VMEbus
is to insure interoperability among vendors.
The new area computers--18 VMEbus
multiprocessor systems--handle the bulk of the real-time traffic control, each managing 576 intersections within a geographic region.
For example, VMEbus
, now 20 years old, has enjoyed a wide acceptance in the medical market, providing complete compute solutions for modalities and laser imagers.
It has a master/slave PCI-to-VME64 bridge on board that enables it to function in multiprocessing applications on the VMEbus
. Its CPU is the 400-MHz MPC8245 Kahlua II PowerPC processor.
In addition to Gigabit speeds the adapter can automatically interface with legacy 10/100 Mb/second networks when used in VMEbus
, CompactPCI or PCI systems.
Xycom, Inc., headquartered in Saline, Michigan, is a worldwide leader in the industrial computer market with a broad product offering including hardened personal computers, industrial workstations for the plant floor, human/machine interface software, and VMEbus
board-level computer products.
But how about VXIbus - VMEbus
eXtention for Instrumentation?
For example, the decommutator board uses the standard VME and VMEbus
subsystem bus (VSB) interfaces for the movement of information.
Their cX platforms are designed for real-time distributed computing and have distributed architectures for 3-, 10-, 12-, and 20-slot VMEbus
