Five Reasons to Use System on Modules (SoM) in Embedded ...

Before delving into any other details, let’s start from the beginning. A module system comprises a small package with all the significant elements of an integrated processing system. This includes everything from processor cores, communication configurations, and memory blocks on a small, production-ready Printed Circuit Board (PCB). A System on Modules is a complete CPU architecture in one tiny container. This approach allows SoM to be embedded in end systems ranging from complicated robots to simple home security cameras.

However, a System on Module should not be confused with a System on a Chip (SoC). An SoC includes a series of crucial compute components, all assembled on one chip. On the contrary, an SoM is based on a board and can include multiple components, and an SoC can be one of these. So, one should keep this in mind while choosing what to incorporate into their technologies.

Blade servers initially led to the development of the system on modules. These small servers were developed to conserve energy use and save storage space. The SOM assembly has been designed in the same sleek style as blade servers, and only the elements necessary for operation are all together in one tiny package. However, this does not prevent them from being used in multiple applications, most of which we will discuss in a moment.

Tessolve provides an extremely integrated software and hardware platform developed for quick advancement and marketing time, along with an assortment of resources and tools for ease of maintenance and scalability of design.

1. Saves time

The primary reason behind the usage of the system on modules for the embedded device is the time-saving aspect. It takes far less time to build a product based on an SoM than to design a complete system from the start. Creating the CPU infrastructure often takes the most effort when it comes to embedded systems. Instead, one can take advantage of an SoM to save time and effort that could be better spent anywhere else. Tessolve provides the best in class, reliable and secure, embedded SOM solution with integrated wireless connectivity.

2. Customization

System on Modules provides a wide range of features and processor speeds in the same packages. This allows businesses to provide the same carrier board with variable speeds. Customers can easily design custom carrier boards that meet all their requirements without individually thinking about the processor and memory. The issue related to complicated custom cables is also eliminated since most businesses will provide pre-wired connectors that match standard cables. With the help of simple process upgrades and downgrades, anyone can create their dream system without spending their entire budget and a lot of time.

3. Simplicity

Another significant reason is the advancement of semiconductor technologies. Designing an embedded system using a SoC or FPGA requires a significant amount of time and care. Since semiconductors are becoming more and more advanced, there is a lot of information and little nuances to consider during the design process. Instead, one can use an SoM and spend the rest of the time focusing on the personality of your product and taking advantage of the complexity.

4. Development cost

A system on module significantly reduces the development cost of developing an embedded system. As we mentioned at the beginning of the article, time is money, and by spending much less time on development work, most of the engineering expense is minimized.

5. Risk at the end of its useful life

The complications related to the end-of-life product based on a flash chipset or an end-of-life CPU are minimized by using a system of modules. The system may be brought back to life with a simple switch without significant carrier board changes. In addition, customers won’t have to worry about spending a lot of money on boards every year since most SoMs have a lifespan of more than five years.

You can obtain reliable SoMs from Tessolve as we also provide evaluation boards for SoM. Tessolve allows faster time to market for customers by offering a seamless shift from development to production and more.

Software and hardware development

Systems on modules can help achieve edge computing and local data processing without latency. This eliminates the requirement for expert hardware knowledge and experience by providing an intuitive design that anyone can apply. In addition, software developers who interfere with vision applications will appreciate the easily configurable sensors provided by SOMs.

Any hardware developer knows that production needs to be completed as quickly as possible, so limited resources should be focused on the highest-impact tasks. A system on modules provides field-programmable gate array (FPGA) performance and flexibility without all the hassle of PCB design and integration. With a powerful and innovative industrial System-on-Modules, integrated security, sophisticated device management tools and systems software, Tessolve’s embedded solutions minimize the expense of ownership and aid propel OEMs to success in the market.

Security cameras

One of the most common applications of SoMs is security cameras. Many system-on-modules provide 4K vision and video processing capabilities, which makes them ideal for such types of applications. These security cameras not only record videos but also use machine learning to categorize and analyze what they see, consistently delivering accurate real-time data.

Wrapping Up

System-on-Modules are the future of embedded systems development. Some of the examples listed above are just a few of hundreds of applications. Especially during the pandemic, home automation is high on people’s priority list, and most of these embedded devices are made with SoM.

Tessolve has its independent SOM Module Family, MAGIK-2 models, depending on the SMARC/Q7 standard, consisting of an entire software suite involving Device Drivers, assistance for different operating systems permitting efficient productization.

What are Embedded Systems? - Sensible Micro

Embedded systems are everywhere. From dishwashers to aeronautical devices, embedded systems are used in a variety of electronics. But what are embedded systems? 

In this post we answer that question, covering how these systems work, advantages and disadvantages, industry applications and sourcing solutions. 

Embedded Systems and How They Work: 

Embedded systems are computer hardware systems that are designed to perform a specific function, either independently or as part of a larger structure. Embedded systems can be simple or very elaborate depending on what they’re designed to do, with complexities ranging from a single microcontroller to a suite of processors with connected networks and peripherals. 

Every embedded system has both software and hardware. The software used for embedded systems is what truly determines its function and is typically called firmware because the single program is stored on a chip as opposed to a disc. The firmware is written to perform a set task and its code is usually housed in non-volatile memory within the hardware. In addition to what it is programmed to do, an embedded system’s firmware also monitors system memory, processor speeds, and because an embedded system runs continuously, the firmware also limits power dissipation for basic actions like run and stop. 

Hardware is vital to an embedded system because it is what the system runs on. The hardware used for an embedded system is based around either a microcontroller or a microprocessor as well as other electronic components. The system is comprised of many different elements, including: 

  • Timers
  • SASC (System application specific circuits)
  • Serial communication ports
  • Processor
  • Power Supply
  • Input/Output circuits
  • Memory
  • Embedded System Software

 Typically, embedded systems that use microcontrollers are more commonly used because microcontrollers need fewer external components. However, if an embedded system is part of a larger structure, a microprocessor-based system would be the best option because they allow for the selection of exact peripherals and expansion. Roughly 98% of all microprocessors manufactured today are used in embedded systems across the electronics industry. 

An embedded system uses its hardware platform to operate and perform its set function. The systems are managed by microprocessors or microcontrollers but can also be managed by other things such as application-specific integrated circuits (ASIC), graphic processing unit (GPU) technology, and Field-programmable gate arrays (FPGA). Embedded systems connect with outside structures via peripherals, linking input and output devices. 

Advantages & Disadvantages of Embedded Systems: 

There are many advantages to embedded systems. Some of the main benefits include: 

  • Faster Time-To-Market
  • Affordable
  • Operate with very little power consumption
  • Low maintenance (end-user servicing rarely needed)
  • Customizable 
  • Reliable (risk reduction)

Although embedded systems are popular, adaptable, and useful there are some disadvantages. For example, due to the fact that these systems are literally embedded into a device, they are hard to repair, update, and replace. Oftentimes, it is cheaper to replace the entire system than it is to repair a single part. Overall, the positives of embedded systems far outweigh the negatives. 

Industries Supported:  

Embedded systems are used in various markets across the electronics industry. Some of the key industries and related applications include:

  • Automotive
    • Engine management systems
    • Cruise control 
  • Consumer Electronics
