1.4.3Engine Integrator

The Engine Integrator defines various Engine configurations. This can include the names of the Engines, as well as the codecs and their names within each Engine, whether each codec is local or remote relative to the application, which groups each codec should be integrated into (for environments which support resource sharing), the name of the Codec Server image if a particular Engine contains remote codecs, etc. This is done via an XDC configuration script (*.cfg).

This script, when run, generates code and build instructions appropriate for the configuration.

The Engine Integrator receives the name of a Codec Server and a list of the codecs it contains from the Server Integrator. Using these, this person creates an Engine configuration file (.cfg) that may reference a Codec Server. (On local-only platforms, the Codec Server is not used.)

The Engine Integrator hands the Engine configuration file to the

Application Author.

The Engine Integrator uses the following resources:

❏Chapter 5 of Codec Engine Application Developer’s Guide (SPRUE67)

❏Configuration Reference.

CE_INSTALL_DIR/packages/xdoc/index.html

❏Example Build and Run Instructions.

CE_INSTALL_DIR/examples/build_instructions.html

❏Example configuration scripts (*.cfg)

1.4.4Application Author

The application uses the Codec Engine APIs (Engine_, VISA, and other utility APIs) to create/delete preconfigured Engine instances, create/delete and interact with codecs, acquire buffers appropriate for the codecs, etc.

Since Codec Engine doesn't perform any I/O, the application is responsible for handling I/O. This includes such task as file access (for example, open/read/write/seek/close) and driver interaction (for example, open/close/ioctl and buffer management).

The Application Author is responsible for building the application code, and for linking "the appropriate content" into the executable image.

The Application Author receives the following:

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.
