Creating a Codec Server

2.2Creating a Codec Server

To create a Codec Server, you perform the following configuration steps:

❏Configure DSP/BIOS through a Tconf script

❏Configure "the rest" of the components through XDC configuration (for example, Framework Components, DSP/BIOS Link, the Codec Engine, etc.).

You will modify the following files:

❏package.xdc. The package definition file.

❏package.bld. The build script.

❏servername.cfg. The Codec Server configuration script.

❏servername.tcf. The DSP/BIOS configuration script.

Optionally, you may modify the following additional files:

❏link.cmd. An optional linker command file.

❏main.c. Contains applications main() function.

To begin creating a Codec Server, use the steps in the following subsections. The examples in this section use the CE_INSTALL_DIR/examples/servers/video_copy example.

So long as the algorithms you want to use implement the xDM interface, the coding needed is limited to a simple main() routine in C code to initialize the Codec Engine. The rest of the integration is by providing configuration information to create the Codec Server.

2.2.1Creating a Package

Follow these steps to set up environment variables to point to various tools used in the build process and to create a directory with files you will modify to create your server.

1)Optionally copy the entire CE_INSTALL_DIR/examples tree to a working directory. This step is optional but recommended so that you have a backup copy.

2)Edit the examples/user.bld file, which defines the locations of content on your development system. Make sure the paths in this file match your paths to the TI codegen tools and other compilers and OS tools referenced in the file. See examples/build_instructions.html for details.

Codec Engine Server specifications

Texas Instruments Codec Engine Server (CES) is a powerful software framework designed to handle audio and video processing on embedded systems. It serves as a bridge between high-level application programming and low-level codec implementations, simplifying the development of multimedia applications. The Codec Engine's primary focus is on optimizing media codecs for applications such as telecommunications, video conferencing, multimedia playback, and streaming services.

One of the standout features of the CES is its ability to support multiple codecs simultaneously, allowing developers to efficiently decode and encode various media formats in real time. This flexibility is crucial for applications that demand high-quality audio and video processing without compromising performance. Furthermore, the CES architecture promotes modular design, enabling developers to swap in and out different codec implementations based on specific project requirements.

The CES leverages advanced technologies including simultaneous multithreading, which maximizes the processing power of multi-core processors. With this capability, developers can allocate threads efficiently across multiple cores, tackling demanding tasks without latency. Additionally, the framework supports dynamic codec allocation, meaning that resources can be managed and adjusted on-the-fly as needed, ensuring optimal performance in varying conditions.

Another significant characteristic of the CES is its compatibility with various Texas Instruments DSP (Digital Signal Processor) platforms. This ensures that developers can take advantage of the specialized capabilities of TI's hardware, including their power management features and high-performance processing capabilities. The integration of hardware and software within the CES architecture allows for optimized resource utilization, leading to energy-efficient applications.

The development process is further streamlined through the use of a comprehensive API (Application Programming Interface) that provides access to codec functionalities while abstracting the complexities of underlying hardware. This allows developers to focus on building high-level features without getting bogged down in low-level programming details.

In conclusion, Texas Instruments Codec Engine Server stands out as a robust solution for developers aiming to create high-performance media applications. Its support for multiple codecs, efficient resource management, and compatibility with TI DSP platforms make it an indispensable tool in the multimedia processing space. By facilitating seamless interaction between hardware and software, CES empowers developers to deliver richer multimedia experiences in their applications.
