Types of Computer on Modules

A computer on module (CoM) is an embedded computing system that is computer-based. It consists of various electronic components such as CPUs, Ethernet interfaces, USB interfaces, and storage devices, among others.

CoM is usually mounted on a single circuit board (SBC) and provides a compact and efficient solution for embedded computing applications. It is designed to be integrated into other systems or products, offering a pre-assembled and tested computing module for developers and manufacturers.

The purpose of the mini embedded computer on module is to speed product development by giving a standard computing module that can be implemented into a variety electronic devices. This helps to reduce the complexities of designing a system from scratch and ensures reliability by using a pre-tested computing solution. It also enables manufacturers to quickly adapt to changes in technology by using updated components on the module when necessary.

Industrial computer on modules offer flexibility in designing embedded systems, efficient computing power, and reliability for a range of applications. Its use accelerates the time-to-market for products incorporating embedded computing within various industries, including automation, healthcare, and consumer electronics.

Types of computer on modules include;

• Type 1 - VxBUS-Based Modules: These are computer modules designed for applications that can be built around the VxBUS API. The kernel and device drivers in these modules run in the same memory space as the application, allowing for efficient communication between the application and the drivers. This design is beneficial for applications that need to interact closely with device drivers.
• Type 2 - Linux-Kernel-Based Modules: This type includes modules with their own Linux kernel and a set of device driver processes. These modules use the resources of the embedded Linux system on the motherboard for Linux tasks, like the device driver processes, that are separate from the applications running in the computer on module. This separation allows for more stability.
• Type 3 - Dual-Use Modules: These hybrid modules combine features from both VxBUS-based and Linux-kernel-based types. They have a VxWorks kernel and device driver processes but also use the Linux resources within the motherboard's embedded Linux system. This dual-use design integrates elements from both the VxBUS-based and Linux-kernel-based modules.

How to Choose a Computer on Module

Various factors are important to consider when selecting a computer-on-module to ensure it meets application requirements.

• Processing needs: The first step is determining the processing needs of the target application. This entails establishing the number of tasks to be performed, their intricacy level, and the processing power required. Afterward, the specific module should be selected based on the computer-on-module type. For instance, the coal mine safety monitoring system can use the ARM-based module, while gaming and multimedia applications that require high processing power can use the Intel-based module.
• IO and Connectivity: Identify the sensors, peripherals, and devices with which the system will interact. Assess the needed input/output interfaces and ensure the module provides the necessary ports and protocols. Consider connectivity requirements like Wi-Fi, Bluetooth, cellular, and other network interfaces needed for data transfer and remote communication.
