New modules for high-end medical computing


Andreas Bergbauer product manager for COM Express at congatec presents the latest AMD Ryzen embedded processors, offering 108% more performance, and increasing overall computing performance by 144% - Two good reasons for congatec to implement the new processors on its COM Express Type 6 modules


C


OM Express Type 6 modules are one of the most widely used form factors


in high-end medical computing. They offer a standardised footprint and standardised interface support, which are being used for custom system designs. Benefits include: a highly integrated super component that comes with an application-ready board support package (BSP) as well as extensive design guides and design templates for custom carrier boards. Compared to full-custom designs, Computer-on-Modules have the potential to cut NRE costs by 50% to 90%. System designs are also easier to certify since the PICMG COM Express module specification already provides extensive documentation and meets the relevant standards. In addition, the ability to use standard-compliant Computer- on-Modules from different manufacturers and different processor configurations extends the longevity of system designs and, above all, makes them easily scalable.


HIGH-PERFORMANCE DEMANDS Scalability is of particular interest for applications that demand the latest processing and graphics performance. In the medical field, this includes applications such as:  Medical imaging, as the more precise the imaging systems are, the better and more effective the diagnosis will be;


 Endoscopy systems for diagnosis and minimally invasive surgery, as the resolution of the images or video streams is crucial here as well;


 Diagnostic stations, as they must quickly present high-resolution content up to 4k and beyond;


 Artificial intelligence (AI) and deep learning systems to support diagnostic decisions or optimise drug delivery and radiotherapy;


 Smart robotics applications for medical surgery and assisted living that in the future will also use deep learning and AI to optimise their situational awareness. The processor’s integrated GPU, which

is based on the very latest AMD Radeon Vega architecture, provides more than twice the graphics performance of its predecessor. Benchmarks in the 15 Watt class show a performance increase of up to 228%. The reason for this enormous performance increase lies in the new Graphics Core Next architecture with higher clock rates and many other improvements. The benefits of this performance


increase include not only faster image frequency calculation in complex high- speed 3D animations, but also more

extensive presentation features. For instance, it is now possible to deliver individual content to four instead of three displays with up to 4k Ultra HD resolution. For particularly realistic images with high contrast and wide colour gamut, the new Vega graphics now also supports High Dynamic Range displays with 10-bit depth per colour channel. This will be of particular benefit to advanced diagnostic systems in medical technology as well as UHD endoscopy systems. For this purpose, video file processing is hardware- accelerated without burdening the CPU; both advanced 10-bit H.265 videos and VP9 material are decoded. Because of the Video Compression Engine 3.1 (H.264), it is further possible to encode two supplied 8-bit full-HD video streams in real time. The new multi-core processors also


provide impressive overall single-thread and multi-thread performance. The new Zen Core, for example, is capable of handling around 52% more instructions per cycle than its predecessor, the Excavator Core. This significant performance increase has its roots in numerous improvements in the new Zen microarchitecture. To give an example, the new AMD Ryzen Embedded processors support simultaneous multithreading (SMT) for the first time. This makes it possible to process two parallel threads, ultimately resulting in even higher throughput. Another relevant feature for maximum performance is the Precision Boost, which individually optimises the clock frequency for each core. The Extended Frequency Range additionally increases the core clock speed as long as thermal reserves are available. All this is provided with a significantly


optimised TDP, which is also crucial for the integration of the new processors into space-constrained medical system designs.
