Version Date Notes
1.0.0 January 2020 First public release

Introduction[edit | edit source]

According to NXP documentation, eIQ Machine Learning Software is a collection of software and development tools for NXP microprocessors and microcontrollers to do inference of neural network AI models on embedded systems.

This Technical Note (TN for short) illustrates hot to use eIQ in combination with Mito8M, DAVE Embedded Systems's latest SoM, which is built upon the i.MX8M processor by NXP.

Testbed[edit | edit source]

With regards to the hardware, the testbed consists of the same platform described MISC-TN-008:_Running_Debian_Buster_(armbian)_on_Mito8M here.

Concerning the software, the following combination was used:

  • U-Boot 2018.03 retrieved from the standard Mito8M Yocto-based Board Support Package (BSP)
  • Device tree retrieved from the standard Mito8M Yocto-based BSP
  • Linux kernel imx8qmmek 4.14.98-imx_4.14.98_2.0.0
  • eIQ-enabled Yocot-based root file system.

For more information about the kernel and the root file system, please refer to the following section.

Building NXP eIQ software[edit | edit source]

NXP document UM11226 illustrates how to build eIQ software support using Yocto Project tools. Even though the official procedure was tested against Ubuntu 16.04, a host running Ubuntu 18.04 was used successfully.

By following step by step the official procedure,

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:

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).

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:

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.
