SPRS268E –MAY 2005 –REVISED JANUARY 2007

SPRAA69 Using the TMS320C672x Bootloader Application Report. This document describes the design details about the TMS320C672x bootloader. This document also addresses parallel flash and HPI boot to the extent relevant.

SPRU301 TMS320C6000 Code Composer Studio Tutorial. This tutorial introduces you to some of the key features of Code Composer Studio. Code Composer Studio extends the capabilities of the Code Composer Integrated Development Environment (IDE) to include full awareness of the DSP target by the host and real-time analysis tools. This tutorial assumes that you have Code Composer Studio, which includes the TMS320C6000 code generation tools along with the APIs and plug-ins for both DSP/BIOS and RTDX. This manual also assumes that you have installed a target board in your PC containing the DSP device.

SPRU198 TMS320C6000 Programmer's Guide. Reference for programming the TMS320C6000 digital signal processors (DSPs). Before you use this manual, you should install your code generation and debugging tools. Includes a brief description of the C6000 DSP architecture and code development flow, includes C code examples and discusses optimization methods for the C code, describes the structure of assembly code and includes examples and discusses optimizations for the assembly code, and describes programming considerations for the C64x DSP.

SPRU186 TMS320C6000 Assembly Language Tools v6.0 Beta User's Guide. Describes the assembly language tools (assembler, linker, and other tools used to develop assembly language code), assembler directives, macros, common object file format, and symbolic debugging directives for the TMS320C6000 platform of devices (including the C64x+ and C67x+ generations). NOTE: The enhancements to tools release v5.3 to support the

C672x devices are documented in the tools v6.0 documentation.

SPRU187 TMS320C6000 Optimizing Compiler v6.0 Beta User's Guide. Describes the TMS320C6000 C compiler and the assembly optimizer. This C compiler accepts ANSI standard C source code and produces assembly language source code for the TMS320C6000 platform of devices (including the C64x+ and C67x+ generations). The assembly optimizer helps you optimize your assembly code. NOTE: The enhancements to tools release v5.3 to support the C672x devices are documented in the tools v6.0 documentation.

SPRA839 Using IBIS Models for Timing Analysis. Describes how to properly use IBIS models to attain accurate timing analysis for a given system.

The tools support documentation is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE).
