How does MATLAB Link for Code Composer Studio Development Tools help students?

Visualize signals and data Design algorithms for individual components Learn processor concepts/commands Grasp implications of

real-time processing

Visualizing signals and data

Signals from:– Signal Processing Toolbox– Real-time DSP

Data from:– CCS Simulator– Real-Time DSP– Other sources, through

MATLAB workspace

Designing algorithms for components

Design• Filters• Transforms• Windows• Converters• PLLs, etc.

Explore design alternatives

• Extensive support

Simulate

Processor concepts/commandsStudents become familiar with memory, read/write,…

Example commands:MATLAB/CCS:

– regwrite - Write a value to a specified register on the target processor

– write - Write data to memory on the target processor

– get - Return the property values for a link to CCS

– MATLAB/RTDX:

– enable - Enable the RTDX interface, a specified channel, or all RTDX channels

– readmat - Read a matrix of data from specified RTDX channels

Implications of real-time

Read/write order Interrupts Cycle times JTAG/RTDX

Embedded Target for C6000 DSP Platform

Generates board-specific C code:

•C6711 DSK •C6701 EVM boards

Creates CCS projects

from C code:compiles links

Runs executable on target board

Using the Embedded Target for C6000 DSP Platform

Design and simulate model from:– DSPBS – Comm – Simulink – Stateflow

Connect board specific blocks– A/D, D/A, LED, DIP Switches, JTAG RTDX
