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. As an example, please see [[SBCX-TN-006:_Characterizing_the_RAM_bandwidth_of_Axel_Lite_SoM#Testbed_general_configuration|this Technical Note]] where we characterized the SDRAM bandwidth of Cortex A9-based Axel Lite SoM. When dealing with computationally heavy tasks, this factor a limited RAM bandwidth efficiency may turn out to be a severe bottleneck limiting bounding the overall performance.

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 benchmark tests that were run on Mito8M SoMto characterize its bandwidth. It is worth to remember that this product Mito8M is built upon the [https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i.mx-applications-processors/i.mx-8-processors/i.mx-8m-family-armcortex-a53-cortex-m4-audio-voice-video:i.MX8M i.MX8M processor by NXP].

This processor is capable of running either at 800 MHz or 1.3 GHz. All the The tests were conducted performed at 800 MHzeither frequencies in order to determine how the it affects the RAM bandwidth.

TBDFor what regards the memory bandwidth, LMbench provides many results organized in different categories. For the sake of simplicity, the following tables details just a couple of categories. The full results are available for download [http://mirror.dave.eu/mito/Mito8M/lmbench-Mito8M.0-800MHz.txt here (ARM core frequency set to 800 MHz)] and [http://mirror.dave.eu/mito/Mito8M/lmbench-Mito8M.0-1300MHz.txt here (ARM core frequency set to 1300 MHz)]. {| class="wikitable"|+Memory read bandwidth! rowspan="2" |Buffer size! colspan="2" |Bandwitdth[MB/s]|-!ARM core frequency = 800 MHz!ARM core frequency = 1300 MHz|-|512B|1553|2521|-|1kB|1567|2546|-|2kB|1575|2560|-|4kB|1575|2564|-|8kB|1577|2564|-|16kB|1577|2567|-|32kB|1528|2490|-| 0.065536 |64kB|1531|2494|-|128kB|1547|2530|-|256kB|1552|2526|-|512kB|1514|2518|-|1MB|1318|2181|-|2MB|1430|2148|-|4MB|1420|2108|-|8MB|1423|2038|-|16MB|1420|2116|-|32MB|1365|2117|-|64MB|1393|2035|-|128MB|1382|2035|-|256MB|1372|2050|-|512MB|1367|1998|} {| class="wikitable"|+Memory write bandwidth! rowspan="2" |Buffer size! colspan="2" |Bandwitdth[MB/s]|-!ARM core frequency = 800 MHz!ARM core frequency = 1300 MHz|-|512B|2932|4771|-|1kB|3048|4956|-|2kB|3100|5046|-|4kB|3136|5097|-|8kB|3135|5101|-|16kB|3150|5120|-|32kB|2864|5127|-|64kB|3033|5071|-|128kB|3093|4886|-|256kB|2956|5056|-|512kB|3024|5054|-|1MB|3075|5092|-|2MB|3095|5116|-|4MB|3121|5118|-|8MB|3137|5120|-|16MB|3145|5121|-|32MB|3146|5120|-|64MB|3146|5125|-|128MB|3147|5123|-|256MB|3150|5124|-|512MB|3144|5125|-|1GB|3146|5124|} There are some interesting facts to stress:* Read and write bandwitdth are not effected by the buffer size.* They are significantly affected by the ARM core frequency. For instance, the improvement of the write bandwidth (about 62% when the buffer is 1GB) is practically the same of the increase in frequency. For more information regarding LMbench, please see [http://lmbench.sourceforge.net/ this page]. 

TBDAs defined by the author, <code>pmbw</code> is "a set of assembler routines to measure the parallel memory (cache and RAM) bandwidth of modern multi-core machines." It performs a myriad of tests. Luckily, it comes with a handful tool that plots the results—which are stored in a text file—in a series of charts. Again,the benchmark was run at two different ARM core frequencies, 800 and 1300 MHz. The complete results and the charts are available at the following links:*http://mirror.dave.eu/mito/Mito8M/pmbw-stats-Mito8M-800MHz.txt*http://mirror.dave.eu/mito/Mito8M/pmbw-plots-Mito8M-800MHz.pdf*http://mirror.dave.eu/mito/Mito8M/pmbw-stats-Mito8M-1300MHz.txt*http://mirror.dave.eu/mito/Mito8M/pmbw-plots-Mito8M-1300MHz.pdf Generally speaking, the charts exhibit significant declines in the performances when the array size is around the L1 and the L2 cache size. For more details about <code>pmbw</code>, please refer to [https://panthema.net/2013/pmbw/ this page]. ===stressapptest===According to the documentation, stressapptest—which was developed at Google—is "a memory interface test. It tries to maximize randomized traffic to memory from processor and I/O, with the intent of creating a realistic high load situation in order to test the existing hardware devices in a computer."{| class="wikitable"|+! rowspan="2" |Test! colspan="2" |Bandwidth[MB/s]|-!ARM core frequency = 800 MHz!ARM core frequency = 1300 MHz|-|Memory copy|5483|5804|}  The above table lists the achieved results when the benchmark was run as detailed in [[#Running_the_tests_4|this section]]. In this case, the different when running at different ARM core frequencies is very little. For more information about stressapptest, please refer to [https://github.com/stressapptest/stressapptest this page].
