Introduction 1 Introduction www.ti.com 1.1 Intended Audience – Expert DSP Engineer New to TI’s Code Composer Studio™ (CCS) CCS is Texas Instruments’ Integrated Development Environment (IDE), based on the open source Eclipse architecture. CCS is used to build, debug, and run DSP applications and other processor applications. TI provides CCS training, documentation, and other help that covers all aspects of CCS. Section 1.2 provides links for the training. The intended audience of this document are DSP experts who have not yet worked with TI tools, yet are knowledgeable and have worked with tools from other vendors. They know what to expect from these tools, understand the logic behind them, and only need to know the mechanics of the tools. They may not have time for training. Their goal is to jump in and try to run a test application. In addition to the CCS tool, TI provides software blocks to facilitate easy development of applications on TI’s devices, including a set of optimized libraries for standard mathematics (MATHLIB), signal processing (DSPLIB), and image processing (IMGLIB). A DSP expert can use these optimized functions in applications. This document shows an expert DSP engineer how to develop applications that call optimized library functions. 1.1.1 Steps to Take When Starting to Port a DSP Algorithm into TI Environments When porting an existing DSP algorithm, developed under a different environment, into TI’s Integrated Development Environment CCS, the expert engineer goes through the following steps: 1. TI’s Processor Software Development Kit (SDK) is a comprehensive set of software and firmware tools, utilities, and example modules that supports many TI processors. Each module has a unit test project that demonstrates how to use the module. To understand how to use a library function, import the unit test of the said function and run it on hardware such as an evaluation module (EVM). Section 2 shows how to import a project from the release, build it, and run it on standard hardware. 2. Build a new application that utilizes the library function used in the previous step. Section 3 shows how to build a new non-trivial (that is, fairly complex) project, build it, and run it on standard hardware such as an EVM. 3. The SDK is a uniform release of software blocks that ensures working together. Three standard libraries are included in the SDK release: DSPLIB, MATHLIB, and IMGLIB. In addition, TI developed a set of optimized libraries that are not part of the Processor SDK release. These libraries include IQMATH, FASTRTS, VICP, VLIB, FAXLIB, and VOLIB (see http://processors.wiki.ti.com/index.php/Software_libraries for more details). In addition, there are devices that are not supported by the standard Processor SDK, but rather by their own SDK. Section 4 shows how to build an example code (unit test) C674X that is not supported by the Processor SDK, using a library function from a dedicated FFTLIB library. 1.2 CCS Online Training Resources • CCS Training Page — contains training materials, including videos and documents. • TMS320C6000 Optimization Workshop — Section 2 discusses CCS (and provides an introduction to C6000 architecture) • The Code Composer Studio (CCS) Integrated Development Environment (IDE) — The location to download CCS, with links to other CCS information • Processor SDK RTOS Setup CCS — An introduction to using CCS with the Processor SDK. Some of the materials referenced in this document are covered here • TI’s Code Composer e2e Forum — A public forum dedicated to questions and answers about everything CCS. Almost any issue that you may encounter has probably been discussed previously in this forum. Code Composer Studio is a trademark of Texas Instruments.

www.ti.com 1.3 Getting Started With CCS Introduction The instructions and the screen shots in this document are taken from CCSv6 (6.1.3). Different versions of CCS might have slightly different screen shots. This document assumes that the user has already installed CCS. CCS puts all the metadata that is associated with its operation in the workspace. There is a default workspace (usually in c:/users/user_name/workspace_v6 or similar, where user_name is the user login name) where multiple projects can reside. In addition, the user can define other locations as workspace for a specific project. The first time CCS is opened in a new workspace, the display window (see Figure 1) provides links to collateral that provide training and other support documents. Figure 1.

Introduction 1.4 CCS Edit and Debug Perspectives www.ti.com CCS has two default perspectives. • The CCS Edit perspective is used for creating projects and building code. To switch to the CCS Edit perspective, click on Window → Perspective → Open Perspective → CCS Edit. • The CCS Debug perspective is used for execution and debugging of code on the customer EVM. To switch to the CCS Debug perspective, click on Window → Perspective → Open Perspective → CCS Debug (see Figure 2). Figure 2. Changing the CCS Perspective The current perspective can be seen in the upper right corner of the CCS window, as shown in Figure 2. Upon starting CCS, the default perspective is the CCS Edit perspective. 4 Introducing TI’s Integrated Development Environment – Code Composer Studio™ (CCS) to Expert Engineers Copyright © 2016, Texas Instruments Incorporated SWRA526–November 2016 Submit Documentation Feedback

www.ti.com 2 Import CCS Project From Release Examples 2.1 Before Importing a Project Import CCS Project From Release Examples The Processor SDK has many examples and unit tests within a release that can be imported into a project. Instructions on how to import a project from a release are provided in this chapter. Most of the examples in the release are based on the real time software component (RTSC) scheme. RTSC enables the system to rebuild drivers and utilities for a user-defined platform from a configuration file. To achieve that, the CCS environment must be aware of the location of the various building modules in the Processor SDK release; in other words, the user must verify that CCS sees all the modules in the release. Assuming a new release was installed in directory C:\ti\Releases\Release_3_0_0_4\C667X, the following steps are required to add or verify that CCS sees the new release. 1. Click the Window tab and select Preferences, as shown in Figure 3. Figure 3.

www.ti.com 3. Import CCS Project From Release Examples In the Product Discovery Path, specify the location of the new release. If the path is not there, click on the Add tab, add the directory name or browse to the directory, and click OK, as shown in Figure 5. Figure 5. Add to Discovery Path 4. CCS scans the new location and reports back any new modules found. Click Finish. CCS adds the new module. 5. A dialogue box may ask if the user trusts the software. Answer Yes, then restart CCS. NOTE: Some releases have issues with multiple NDK releases. If CCS reports an error when it loads NDK, un-checks NDK before clicking on Finish.

Import CCS Project From Release Examples 2.2 Import the FFT Project This next section uses an FFT project as an example. To get started, left-click on the Project tab in the CCS EDIT perspective, then select import CCS Projects as shown in Figure 6, and left-click. www.ti.com Figure 6. Import CCS Projects A dialog box is opened. For the Select search-directory, click on Browse and navigate to the location where the DSPLIB directory was installed on the system → examples, and select OK. CCS searches for all the examples in this directory. 8 Introducing TI’s Integrated Development Environment – Code Composer Studio™ (CCS) to Expert Engineers Copyright © 2016, Texas Instruments Incorporated SWRA526–November 2016 Submit Documentation Feedback
