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.

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.
