This procedure provides an overview of how to compile and run the fbench C example project. It assumes familiarity with the C programming language and is intended to be used by experienced programmers who are looking to learn the EMAC SDK.
Contents
1. Open the C/C++ editing perspective
2. Open the egpc project
3. Build, upload and run
What it does
This is a benchmarking program for determining floating point accuracy and performance. This project creates 2 programs : fbench and ffbench. fbench benchmarks using one algorithm, ffbench uses another. See project comments for details.
Usage for fbench:
fbench <itercount>
Where <itercount> is an optional specification for the number of iterations to be executed, 1000 being the default.
i.e. : ./fbench 123
It runs until it is finished and then outputs the results. hey mike fbench just seems to hang, never outputs results. maybe the board is just slow. I dunno
Usage for ffbench:
ffbench i.e. : ./ffbench
It runs until it is finished and then outputs to the terminal whether or not errors were detected in it's results.
