Abaco Systems VMIVME-3122-210

Overview

The Abaco Systems VMIVME-3122-210 is a high-performance single-board computer (SBC) based on the VME (VersaModule Eurocard) bus architecture. Specifically designed for industries with strict reliability and real-time requirements, such as industrial automation, aerospace, and defense, it integrates powerful computing performance, rich I/O interface configurations, and high-reliability design. Capable of stable operation in complex and harsh environments, it provides efficient data processing and precise control support for critical mission systems, serving as an ideal choice for building high-performance embedded computing platforms.

Functional Features

Efficient Computing Performance

Equipped with a high-performance processor, it delivers robust instruction execution and multi-task processing capabilities, rapidly responding to and handling real-time data in industrial production, high-precision navigation calculations in aerospace, and complex signal processing tasks in military systems. Combined with large-capacity memory and high-speed storage, it significantly enhances data processing efficiency, ensuring smooth operation under high-load scenarios and meeting various high-intensity computing requirements.

Diverse Interface Configurations

High-Speed Network Interfaces: Integrated Ethernet ports support 10/100/1000Mbps communication, enabling high-speed data interaction, remote monitoring, and management with external networks.
General I/O Interfaces: Multiple serial ports, USB interfaces, and GPIO ports facilitate connection to peripherals (sensors, actuators, storage devices) for efficient data transmission and device control.
Dedicated VME Bus Interface: Seamlessly integrates with other VME devices, allowing flexible system expansion to build complex distributed computing systems via data acquisition modules, communication modules, etc.

High Reliability and Stability

Adopting industrial-grade design and manufacturing processes, it features excellent resistance to electromagnetic interference, vibration, and shock, operating stably in harsh environments (high/low temperature, humidity, dust). A built-in fault diagnosis and self-protection mechanism monitors operational status in real-time, triggering alarms and protective measures for anomalies (hardware failure, voltage fluctuations, overheating), reducing system failure risks and maintenance costs while ensuring long-term stable operation.

Flexible Software Adaptability

Supporting multiple mainstream operating systems—including real-time OS (e.g., VxWorks) and general-purpose OS (e.g., Linux, Windows)—users can freely choose platforms based on application needs. This facilitates software development and system integration, enabling optimal adaptation for both real-time industrial control programs and conventional data processing/analysis software across diverse scenarios.

Working Principle

System Boot Process

Power Conditioning: The power management module filters and stabilizes input voltage to supply reliable power to components.
BIOS Initialization: The processor loads BIOS from onboard flash, initializing hardware (memory self-check, I/O interface configuration, bus frequency/address setup).
OS Loading: BIOS boots the OS kernel and drivers from specified storage (HDD/SSD) per the preset sequence, completing startup.

Data Processing Flow

External data (e.g., industrial sensor data or network commands) is transmitted to memory via I/O interfaces.
The CPU processes data per pre-programmed algorithms, storing results in memory or outputting to external devices (displays/actuators).
The OS allocates CPU resources via task scheduling to ensure efficient multi-task execution.

Bus Communication Principle

Based on VME bus architecture, the VMIVME-3122-210 communicates with other VME devices via the VME bus interface, adhering to protocols for data transmission, address allocation, and bus arbitration. As a master, it initiates data transfers; as a slave, it responds to requests. A bus arbitration mechanism resolves concurrent bus access by prioritizing devices, ensuring accurate and efficient data transmission for collaborative system operation.
