Porting Legacy DSC Applications to Freescale’s 32-bit DSC Family

Run DSP Test Sample Projects on an MC56F84789!

 

Previously the huge collection of Processor Expert Example programs for the DSP5685x devices was not easy to run on recent devices such as the MC56F84789.

That is all changed with the publication of Application Note AN4837, available from www.freescale.com.

Also, the note is published with projects for both CodeWarrior for DSC version 8.3, and CodeWarrior for MCU 10.5.

 

Abstract

 

The DSP test programs (FIR, IIR, auto-correlation), included

 

with Freescale’s CodeWarrior 8.3 for DSC, run as delivered

 

in Processor Expert sample projects supplied for the

 

DSP56858. This application note will step the user through

 

conversion of these projects to an Eclipse-based

 

CodeWarrior 10.5 application for the MC56F84789 featured

 

on the TWR-56F8400. This enables the rich collection of

 

software available for the DSP5685x to be used on the latest

 

DSCs from Freescale, as well as the porting of customer

 

projects to such devices. The algorithms presented in this

 

document are not dependent on peripheral differences

 

between various DSC devices. This technique is generally

 

applicable to all such use cases. This note’s intended

 

audience consists of those with interest in the DSC,

 

regardless of Integrated Development Environment (IDE)

 

experience.
