Tips for CMSIS-DSP simulation?

[slintone]

Hi All,

This may not be 100% nRF-related, but:

I have a set of algorithms that are written with Keil uVision 5 for nRF52840 using the CMSIS-DSP library. Now, I would need to simulate the exact output of these algorithms using an x86 computer. The optimal situation would be, that I could make test runs where I could route data from an input file to the algorithms, and write the output to another file. 

One solution could be to try to modify the CMSIS-DSP library so that it would compile for x86. Then the whole project could be made to compile on x86. I have done something like this in the history, but it is a lot of work, and not as good a proof for a working algorithm than running a real processor simulator with a real ARM binary.

Any tips for the easiest way forward? I think the need is quite common?

Hi,

You can use the Jumper Virtual Lab (https://jumper.io) for simulating the ARM CMSIS-DSP library. Jumper Virtual Lab is an alternative for QEMU. It's an emulation platform that is built around a behavioral simulation model of the HW - the MCU core, MCU peripheral and external sensors, and peripherals. Jumper has a support for the nRF52 and the ARM CMSIS-DSP library.

Jumper Virtual Lab allows you to run unit testing and full system tests with a Python SDK. It also supports rapid development and debugging capabilities (with integration to any GDB client).

Let me know if you have any questions.

Good luck!
