III. Working Principle

(1) System Startup Process

When the VMIVME-7700-111000 is connected to the VMEbus system and powered on, the onboard power management circuit first converts, stabilizes, and filters the input power to provide stable and adaptive working voltages for internal components of the device, such as the processor, memory, and various interface circuits. Subsequently, the processor reads the startup code from storage devices (such as built-in CompactFlash or storage devices connected via the IDE interface) and loads the operating system kernel and related drivers. During this process, the BIOS comprehensively detects and configures the system's hardware resources, including memory initialization, timer setup, I/O interface initialization, etc., to ensure all parts of the device are in normal working condition, preparing for subsequent data processing and task execution. If the device is configured with a network boot function, after completing basic hardware initialization, it can obtain startup files from a remote server via the Ethernet controller according to relevant network protocols to complete system startup.

(2) Data Processing Mechanism

In the data processing process, when the system receives external data processing task instructions, the processor parses and computes the tasks according to preset programs and algorithms. Taking industrial automation control as an example, when sensors collect real-time data on equipment operation, the data is transmitted to the processor through corresponding I/O interfaces. The processor uses its powerful computing capabilities to quickly analyze this data and determine the equipment's operating status. During the operation process, the processor frequently interacts with the onboard memory, reading required data from the memory and timely storing operation results back into the memory. At the same time, with the high-speed cache mechanism inside the processor, data that may be frequently used is pre-stored in the high-speed cache to reduce data reading time and improve operation efficiency. For data requiring complex operations, such as statistical analysis of a large amount of historical data in data analysis applications, the processor can quickly handle complex logical operations and data manipulations to ensure the accuracy and timeliness of analysis results.

(3) Data Transmission Principle

VMEbus Data Transmission: The device transmits data with external devices through the VMEbus. When communicating with other VMEbus devices, data is orderly transmitted between devices through address lines, data lines, and control lines under the specification of the VMEbus protocol. For example, in an industrial automation production line, as the main controller, VMIVME-7700-111000 needs to interact with multiple slave devices. Through the VMEbus, it can quickly and accurately send control instructions to slave devices and receive data fed back by slave devices.
Ethernet Data Transmission: For the onboard Ethernet controller, when performing network data transmission, it follows the Ethernet protocol to encapsulate and decapsulate data. When the device needs to send locally processed data to other devices in the network, the data is first transmitted to the Ethernet controller, which encapsulates the data into Ethernet frames according to Ethernet standards and sends them to the network through the Ethernet port; when receiving data, the process is reversed—the Ethernet controller receives Ethernet frames from the network, decapsulates them, and transmits the data to the processor or memory for subsequent processing. For example, in a remote monitoring system, the device transmits collected data to a remote server via Ethernet, facilitating managers to view equipment operation status remotely.
Data Transmission via Other Interfaces: In serial communication, data is transmitted bit by bit in bytes according to the serial communication protocol, achieving low-speed and stable communication between the device and serial devices. USB interface data transmission follows the USB protocol, capable of quickly transmitting large amounts of data, suitable for scenarios such as external storage devices and input devices. Analog I/O interfaces convert analog signals to digital signals (during collection) or digital signals to analog signals (during output) to achieve processing and control of analog quantities; digital I/O interfaces directly perform high-low level input and output operations on digital signals to achieve logical control of digital devices.
