Introduction[edit | edit source]
Mito8M is the first DAVE Embedded Systems' system-on-module (SoM) based on a core implementing the ARMv8-A architecture. Traditionally, ARM cores that are based on 32-bit ARMv7-A architecture exhibit a limited RAM bandwidth even if they are coupled with 64-bit width SDRAM banks. As an example, please see this Technical Note where we characterized the SDRAM bandwidth of Cortex A9-based Axel Lite SoM. When dealing with computationally heavy tasks, a limited RAM bandwidth efficiency may turn out to be a severe bottleneck 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 benchmark tests that were run on Mito8M SoM to characterize its bandwidth. It is worth to remember that Mito8M is built upon the i.MX8M processor by NXP.
Testbed general configuration[edit | edit source]
This section illustrates the configuration settings common to all the tests performed. Basically, the testbed that was used is the same described in this TN.
SoC and SDRAM bank[edit | edit source]
The SoC model is i.MX8M Quad:
armbian@Mito8M:~/devel/lmbench/tmp$ lscpu Architecture: aarch64 Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: ARM Model: 4 Model name: Cortex-A53 Stepping: r0p4 CPU max MHz: 1300.0000 CPU min MHz: 800.0000 BogoMIPS: 16.66 L1d cache: unknown size L1i cache: unknown size L2 cache: unknown size NUMA node0 CPU(s): 0-3 Flags: fp asimd evtstrm aes pmull sha1 sha2 crc32 cpuid
This processor is capable of running either at 800 MHz or 1.3 GHz. The tests were performed at either frequencies in order to determine how the it affects the RAM bandwidth.
The following table details the characteristics of the SDRAM bank connected to the SoC.

Software configuration[edit | edit source]
- Linux kernel: 4.14.98
- Root file system: Debian GNU/Linux 10 (buster)
- Architecture: aarch64
- Governor: userspace @ 800 MHz or 1300 MHz

Some benchmarks were built natively on the platform under test. For the sake of completeness, the version of the GCC compiler is then indicated as well:
armbian@Mito8M:~/devel/lmbench$ gcc -v Using built-in specs.

Overall results[edit | edit source]
This section illustrates the overall results achieved by the benchmarks.

| Add | 6762 | 51.6 | 14.6 |
| Triad | 6354 | 48.5 | 14.9 |
Apart from the increase over Axel Lite in absolute terms, it is noteworthy that Mito8M exhibits a significant improvement in terms of efficiency too, as shown in the above tables. This is especially true in the case of ARM core frequency set to 1300 MHz.
Another interesting thing to note is how the bandwidth is affected by the ARM core frequency. If it scaled linearly, we should have an improvement of 62.5% from 800 to 1300 MHz. The average bandwidth at 800 MHz is 5761 MB/s. At 1300 MHz, it is 6935 MB/s. Therefore, the increase is 20.4%. With regard to STREAM benchmark, the achieved bandwidth does not scale linearly with ARM core frequency.
Please see this page for more details about STREAM benchmark.
LMbench[edit | edit source]
For 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 here (ARM core frequency set to 800 MHz) and here (ARM core frequency set to 1300 MHz).

| 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 this page.
pmbw[edit | edit source]
As defined by the author, pmbw 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 pmbw, please refer to this page.
stressapptest[edit | edit source]
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."
| Test | 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 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 this page.

----------------------------------------
You need to configure some parameters to lmbench. Once you have configured
these parameters, you may do multiple runs by saying
"make rerun"
in the src subdirectory.
NOTICE: please do not have any other activity on the system if you can
help it. Things like the second hand on your xclock or X perfmeters
are not so good when benchmarking. In fact, X is not so good when
benchmarking.
=====================================================================
If you are running on an MP machine and you want to try running
multiple copies of lmbench in parallel, you can specify how many here.
Using this option will make the benchmark run 100x slower (sorry).
NOTE: WARNING! This feature is experimental and many results are
known to be incorrect or random!
MULTIPLE COPIES [default 1]:
=====================================================================
Options to control job placement
1) Allow scheduler to place jobs
2) Assign each benchmark process with any attendent child processes
to its own processor
3) Assign each benchmark process with any attendent child processes
to its own processor, except that it will be as far as possible
from other processes
4) Assign each benchmark and attendent processes to their own
processors
5) Assign each benchmark and attendent processes to their own
processors, except that they will be as far as possible from
each other and other processes
6) Custom placement: you assign each benchmark process with attendent
child processes to processors
7) Custom placement: you assign each benchmark and attendent
processes to processors
Note: some benchmarks, such as bw_pipe, create attendent child
processes for each benchmark process. For example, bw_pipe
needs a second process to send data down the pipe to be read
by the benchmark process. If you have three copies of the
benchmark process running, then you actually have six processes;
three attendent child processes sending data down the pipes and
three benchmark processes reading data and doing the measurements.
Job placement selection [default 1]:
=====================================================================
Hang on, we are calculating your timing granularity.
OK, it looks like you can time stuff down to 5000 usec resolution.
Hang on, we are calculating your timing overhead.
OK, it looks like your gettimeofday() costs 0 usecs.
Hang on, we are calculating your loop overhead.
OK, it looks like your benchmark loop costs 0.00000136 usecs.
=====================================================================
Several benchmarks operate on a range of memory. This memory should be
sized such that it is at least 4 times as big as the external cache[s]
on your system. It should be no more than 80% of your physical memory.
The bigger the range, the more accurate the results, but larger sizes
take somewhat longer to run the benchmark.
MB [default 2097]: 1024
Checking to see if you have 1024 MB; please wait for a moment...
1024MB OK
1024MB OK
1024MB OK
Hang on, we are calculating your cache line size.
OK, it looks like your cache line is 64 bytes.
=====================================================================
lmbench measures a wide variety of system performance, and the full suite
of benchmarks can take a long time on some platforms. Consequently, we
offer the capability to run only predefined subsets of benchmarks, one
for operating system specific benchmarks and one for hardware specific
benchmarks. We also offer the option of running only selected benchmarks
which is useful during operating system development.
Please remember that if you intend to publish the results you either need
to do a full run or one of the predefined OS or hardware subsets.
SUBSET (ALL|HARWARE|OS|DEVELOPMENT) [default all]:
=====================================================================
This benchmark measures, by default, memory latency for a number of
different strides. That can take a long time and is most useful if you
are trying to figure out your cache line size or if your cache line size
is greater than 128 bytes.
If you are planning on sending in these results, please don't do a fast
run.
Answering yes means that we measure memory latency with a 128 byte stride.
FASTMEM [default no]:
=====================================================================
This benchmark measures, by default, file system latency. That can
take a long time on systems with old style file systems (i.e., UFS,
FFS, etc.). Linux' ext2fs and Sun's tmpfs are fast enough that this
test is not painful.
If you are planning on sending in these results, please don't do a fast
run.
If you want to skip the file system latency tests, answer "yes" below.
SLOWFS [default no]: yes
=====================================================================
This benchmark can measure disk zone bandwidths and seek times. These can
be turned into whizzy graphs that pretty much tell you everything you might
need to know about the performance of your disk.
This takes a while and requires read access to a disk drive.
Write is not measured, see disk.c to see how if you want to do so.
If you want to skip the disk tests, hit return below.
If you want to include disk tests, then specify the path to the disk
device, such as /dev/sda. For each disk that is readable, you'll be
prompted for a one line description of the drive, i.e.,
Iomega IDE ZIP
or
HP C3725S 2GB on 10MB/sec NCR SCSI bus
DISKS [default none]:
=====================================================================
If you are running on an idle network and there are other, identically
configured systems, on the same wire (no gateway between you and them),
and you have rsh access to them, then you should run the network part
of the benchmarks to them. Please specify any such systems as a space
separated list such as: ether-host fddi-host hippi-host.
REMOTE [default none]:
=====================================================================
Calculating mhz, please wait for a moment...
I think your CPU mhz is
798 MHz, 1.2531 nanosec clock
but I am frequently wrong. If that is the wrong Mhz, type in your
best guess as to your processor speed. It doesn't have to be exact,
but if you know it is around 800, say 800.
Please note that some processors, such as the P4, have a core which
is double-clocked, so on those processors the reported clock speed
will be roughly double the advertised clock rate. For example, a
1.8GHz P4 may be reported as a 3592MHz processor.
Processor mhz [default 798 MHz, 1.2531 nanosec clock]:
=====================================================================
We need a place to store a 1024 Mbyte file as well as create and delete a
large number of small files. We default to /var/tmp. If /var/tmp is a
memory resident file system (i.e., tmpfs), pick a different place.
Please specify a directory that has enough space and is a local file
system.
FSDIR [default /var/tmp/lmbench]: /tmp/lmbench
=====================================================================
lmbench outputs status information as it runs various benchmarks.
By default this output is sent to /dev/tty, but you may redirect
it to any file you wish (such as /dev/null...).
Status output file [default /dev/tty]:
=====================================================================
There is a database of benchmark results that is shipped with new
releases of lmbench. Your results can be included in the database
if you wish. The more results the better, especially if they include
remote networking. If your results are interesting, i.e., for a new
fast box, they may be made available on the lmbench web page, which is
http://www.bitmover.com/lmbench
Mail results [default yes]: no
OK, no results mailed.
=====================================================================
Confguration done, thanks.
