Preface
About Developer’s Kit for Texas Instruments DSP
Developer’s Kit for Texas Instruments™ DSP lets you use Simulink® to model
digital signal processing algorithms from blocks in the DSP Blockset, then use
Real-Time Workshop® to generate (or build) ANSI C code targeted to the
TMS320C6701 EVM (C6701 EVM) or TI Code Composer Studio™ Integrated
Development Environment (CCS IDE). The developer’s kit takes the generated
C code and uses Texas Instruments (TI) tools to build C6701 EVM specific
machine code. The build process downloads the targeted machine code to the
evaluation module and runs the executable on the C6701 Digital Signal
Processor (C6701 DSP). After downloading the code to the board, your digital
signal processing (DSP) application runs automatically on the evaluation
module.
To support code generation for your C6701 EVM, Developer’s Kit offers two
targets:
• Target for C6701 Evaluation Module — use Real-Time Workshop to generate
executable code that runs on the C6701 Evaluation Module.
• Target for Code Composer Studio™ Integrated Development
Environment — use Real-Time Workshop to create a project in CCS IDE and
populate the new project with files from the code generation process.
Texas Instruments produces the TMS320C6701 Evaluation Module (C6701
EVM) to help developers create digital signal processing applications for the
Texas Instruments TMS320C6701 processor (C6701 DSP). You can create,
test, and deploy your processing software and algorithms or filters on the
target processor without the difficulties inherent in starting with the digital
signal processor itself and building the support hardware to test the
application on the processor. Instead, the C6701 EVM provides the input
hardware, output hardware, timing circuitry, memory, and power for the
C6701 DSP. TI provides the software tools, such as the C compiler, linker,
assembler, and integrated development environment, for PC users to develop,
download, and test their algorithms and applications on the C6701 EVM.
In addition to generating code to target the C6701 EVM, Developer’s Kit
provides two components that work with and use TI Code Composer Studio™
Integrated Development Environment (CCS IDE) and TI Real-Time Data
Exchange (RTDX™):
