Xeon-D Vs Xeon-E for embedded radar applications: Comparing server-class devices for Space Time Adaptive Processing applications

June 19, 2017

For airborne radars, longer, higher and further means more processing power in smaller, rugged packages. Processing power is achieved by leveraging the best commercial Intel Xeon compute capability. Xeon processors are available as either “mobile” (Xeon D) of “data center” (Xeon E) devices. Xeon D, designed for laptop applications, require lower power, less cores, lower memory bandwidth and less connectivity. Xeon E processors power data-centers and cloud facilities. Such processors typically have larger core counts, faster memory and increased connectivity such as QPI enabling efficient use of multiple on-board processors and SMP.

Embedding Xeon E devices in to military applications requires rugged packaging, efficient cooling, and fast, unrestricted pipes and memory banks. How do these embedded blades with data-center performance perform? In the past, Space Time Adaptive Processing (STAP) was a challenge for embedded systems. This paper studies STAP processing approaches using Xeon D and E processors for comparison.
