cFE Performance Evaluation Kit

Intended to evaluate NASA's cFE on a GomSpace NanoMind A712D.

Right now only a few custom benchmarks:

• app_ping - How many round trip messages (right now just empty) can be sent between two apps in a second.
• benchmarks - Common benchmark utilities such are Whetstone and Dhrystone
• hw_ping - How many round trip messages between an app and a piece of hardware be send in a second. Reads a parameter from a Sinclair Planetary reaction wheel over I2C. Depends on I2C initialization speed. Should add different hardware / interfaces.
• flat_sat - Not working. Intended to simulate real flight software with multiple pieces of hardware and computation intensive software (ACS).

• ./new_app/ - A script (new_application.py) that creates a slew of files based off of template files and using the names provided in var.table. Based off of the cFE sample_app.
• `update_app.sh - Script to copy files into the build directory for an application (for CFS). Should really be part of Make system if I could figure it out.

cFE - To run a benchmark in cFE:

• Copy apps from cpek/cFE/<benchmark>/apps/ into app folder of a fresh cFE install.
• Update the apps:
  • For each app, run sh update_app.sh <app_name> from the platform build directory (build//`)
• Copy corresponding Makefile from cpek/cFE/<benchmarks>/ into build/<platform>/
• Copy cpek/cFE/<benchmark>/startuptable.c to build/<platform>/startuptab/ (nanomind platform only).
• Copy cpek/cFE/<benchmark>/cfe_es_startup.scr to build//exe/`
• From top level of cFE source, run . ./setvars.sh
• From /build/<platform>/ run make
• From /build/<platform>/nanomind run make program (nanomind only)
• Make sure to update the run script on the nanomind as well (using csp-term)

FreeRTOS - To run a benchmark in FreeRTOS:

• Copy files from cpek/FreeRTOS/<benchmark>/include and cpek/FreeRTOS/<benchmark>/src into the corresponding folders of a fresh FreeRTOS source (from GomSpace) directory.
• From top level for FreeRTOS source:
  • ./configure-a712-nostorage.sh
  • ./waf build
  • ./waf program

Dhrystone - Original is from: http://zenit.senecac.on.ca/wiki/index.php/Dhrystone_howto

Modified to run on the NanoMind in a cFE app / FreeRTOS task. wget http://www.sfr-fresh.com/unix/privat/old/dhrystone-2.1.tar.gz tar xf dhrystone-2.1.tar.gz

Update the Makefile, make, and run (enter at least 100000000)

Divide result by 1757 to convert to DMIPS.
