About this Example
|
||
|
|
==================
|
||
|
|
This directory contains a QP code used for performance measurements,
|
||
|
|
as described in the "Application Note: QP/C++ Performance Tests and
|
||
|
|
Results" (http://www.state-machine.com/doc/AN_QP-Cpp_Performance.pdf)
|
||
|
|
|
||
|
|
The performance measurements are performed on the EFM32-SLSTK3401A
|
||
|
|
board (Pearl Gecko Starter Kit) with the IAR EWARM toolset.
|
||
|
|
|
||
|
|
|
||
|
|
The Test Code
|
||
|
|
=============
|
||
|
|
The test code used for preformance testing is the slighlty modified
|
||
|
|
Dining Philosophers Problem (DPP) application. To avoid any manual
|
||
|
|
mistakes, the application code is generated by the QM modeling tool.
|
||
|
|
Two QM models are provided:
|
||
|
|
|
||
|
|
dpp_qhsm.qm - uses the QHsm-based state machine implementation
|
||
|
|
strategy
|
||
|
|
dpp_qmsm.qm - uses the QMsm-based state machine implementation
|
||
|
|
strategy
|
||
|
|
|
||
|
|
To apply the specific implemenation strategy, you need to generate
|
||
|
|
code from one model or another *before* you build the target code.
|
||
|
|
|
||
|
|
|
||
|
|
The Development Toolset
|
||
|
|
=======================
|
||
|
|
The performance testss are done with the IAR EWARM version 7.60
|
||
|
|
toolset. The measurements are generally done by taking differences
|
||
|
|
in the CYCLECOUNTER register avaialable in the Pearl Gecko CPU.

Support Code for EFM32-SLSTK3401A Board
|
||
|
|
=======================================
|
||
|
|
The directory 3rd_party\efm32pg1b contains the CMSIS-compliant
|
||
|
|
device code for the EFM32PG1B200F256GM48 MCU. Please see the README.txt
|
||
|
|
file in this folder for more details.
