EIZO Rugged Solutions explains some key advantages of using a 3U VPX Single Board Computer (SBC) with a System on a Module (SoM) over a dual card solution that uses both a XMC and VPX module configured together in a high-performance mission system.
What is a System on Chip vs. a System on Module?
A System on Chip (SoC) is a highly Integrated Circuit (IC) that combines the functionality of multiple components into a single chip, including microprocessors, I/O interfaces, and various hardware accelerators. SoCs are designed to provide high performance, low power consumption, and compact size, making them ideal for SWaP-C-constrained high-performance embedded computing systems.
A System on a Module (SoM) takes this concept further by integrating an SoC IC with other parts like Memory onto a PCB and then routing all I/O to a high-speed connector. While more limiting in design footprint than a base SoC, it reduces software integration complexity. It also improves overall design reliability as the complex interconnects are thoroughly vetted by the chip design company.
Why are SoMs used in High-Performance Embedded Computing (HPEC) Systems?
The SoMs we focus on typically have powerful CPUs, GPUs, video encode/decode engines, and other hardware accelerators (such as Tensor Cores) to improve the throughput of specific tasks like data processing, Deep Learning (DL), and Vision Acceleration, all of which is done with a relatively small footprint.
The value of SoMs is that all this is included within a single entity which allows better optimization via shared buses and enables built-in security features to be more easily integrated to ensure the protection of sensitive data and the prevention of unauthorized access. This is critical for SWaP-C-constrained HPEC systems, where high throughput processing is essential for system control, feedback, and decision-making tasks.
Reduced Latency & Higher Bandwidth
SoMs have an integrated shared memory controller between their various components, significantly minimizing unnecessary memory copies over a potentially bottlenecked bus found in various dual-card solutions that rely on independent memory fabrics.
For example, dual-card solutions with GPU XMC and SBC VPX modules require data to be transferred between these cards via a PCIe fabric. This discrete memory copying between each device’s memory bank must also be tightly arbitered by the CPU, creating data bandwidth challenges and limiting the designers’ ability to streamline operations and achieve performance goals.
There are several other advantages to using a 3U VPX Single Board Computer (SBC) with an SoC over a dual card solution with XMC and VPX modules as well including:
Reduced Size, Weight, and Power (SWaP): A 3U VPX single board computer with an SoC combines the functionality of multiple cards into a single, compact solution. This reduces the SWaP consumption of the overall system, making it more suitable for applications that require low SWaP processing capabilities.
Higher Performance: SoMs have higher performance per watt than XMC and VPX modules, thanks to their integrated hardware accelerators and shared memory fabric.
Improved Reliability: A single-board computer with SoM is less prone to hardware failures than a dual-card solution, as it eliminates multiple other inter-card connections, which can all be points of failure.
Easier Integration: A 3U VPX single board computer with an SoM simplifies system integration, as it requires fewer cards and components to be integrated at the end site. This also reduces long-term maintenance complications as a single source provides the complete solution.
