Mito8M is the first DAVE Embedded Systems' system-on-module (SoM) based on a core implementing the [https://en.wikipedia.org/wiki/ARM_architecture#64/32-bit_architecture ARMv8-A] architecture. Traditionally, ARM cores that are based on 32-bit [https://en.wikipedia.org/wiki/ARM_architecture#AArch32 ARMv7-A] architecture exhibit a limited RAM bandwidth even if they are coupled with 64-bit width SDRAM banks. When dealing with computationally heavy tasks, this RAM bandwidth factor may turn out to be a severe bottleneck bounding the overall performance, especially in regard to the SoC's used to build embedded systems. For this reason, characterizing RAM bandwidth is useful when dealing with such applications.

Besides an intrinsic increased computational power over their predecessors, ARMv8-A-based SoC's are also expected to improve RAM bandwidth significantly. This technical note (TN for short) illustrates several benchmarking tests that were run on Mito8M Axel Lite SoM to characterize this bandwidth. It is worth to remember that Mito8M This SoM is built upon the [https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i.mx-applications-processors/i.mx-86-processors/i.mx-8m6quad-processors-familyhigh-performance-3d-armcortexgraphics-a53hd-cortexvideo-m4arm-audiocortex-voicea9-videocore:i.MX8M MX6Q i.MX8M processor MX6Q/D/DL/S family of processors by NXP].
