GE MVME5500 series VME single board computer

GE MVME5500 series VME single board computer

Product Overview

The MVME5500 series is the latest flagship product of Motorola's VME product line. It is a high-performance VMEbus single board computer (SBC) that uses the latest MPC7455 processor and can run at speeds of 1 GHz and above, making it ideal for data intensive applications. It not only provides faster processor performance, but also achieves balanced performance in terms of processor, memory, local bus, and I/O subsystems, enabling higher levels of performance in a single VMEbus slot, meeting the needs of original equipment manufacturers (OEMs) in markets such as defense and aerospace, industrial automation, and medical imaging. At the same time, it provides customers with migration paths to upgrade from multiple legacy boards.

Core Features

Processor and Cache: Equipped with MPC7455 processor, with a speed of 1 GHz or above, 256KB on-chip L2 cache and 2MB L3 cache, and equipped with AltiVec coprocessor, suitable for high-performance computing applications.

Memory: Onboard 512MB SDRAM with ECC, expandable by an additional 512MB through a memory mezzanine card, with a total memory capacity of up to 1GB.

Storage: 40MB flash memory (32MB soldered, 8MB slot style), 32KB NVRAM (4KB available for users).

Bus and Expansion: Dual PCI bus and dual PMC sites, with a bus speed of up to 66 MHz; 64 bit PCI expansion mezzanine connector, capable of supporting up to four additional PMCs.

Network interface: Gigabit Ethernet interface and 10/100BaseTX Ethernet interface.

Compatibility: Compatible with MVME51xx series I/O, even if fully configured with two PMC modules or one PMC module and an additional memory mezzanine, it only occupies a single VME slot and supports multiple migration paths and different P2 I/O modes.

Firmware and Software: Equipped with innovative firmware (MotLoad), supporting multiple operating systems and kernels, providing relevant libraries and built-in testing software.
