Overview

2.1Overview

As described in Section 1.4.2, Server Integrator, the Server Integrator provides a Codec Server to the Engine Integrator. In practice, these roles may be shared by one person.

There are two configuration steps that the Server Integrator performs:

Configure DSP/BIOS through a Tconf script

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

The Server Integrator receives various Codec packages from Algorithm Creators, as well as packages of other components in the system (for example Framework Components and Codec Engine).

The Server Integrator uses Codec Engine and its dependent packages (DSP/BIOS, DSKT2, etc.) along with the XDC Tools to create the following:

A server configuration file (.cfg)

A server DSP/BIOS configuration file (.tcf)

A simple main() routine to do minimal initialization

A DSP executable created by executing the configuration scripts, and combining the various packages. This executable is a Codec Server.

The Server Integrator should also provide a list of the codecs in the

Codec Server.

The Server Integrator hands the DSP executable to the Engine Integrator, who references it in the Engine configuration file. For example, the ceapp.cfg file might contain an Engine configuration and the following line to identify the Codec Server used by the Engine.

vcr.server = "./video_copy.x64P";

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.
