Overview

■Any algorithm scratch memory is then "deactivated".

■The skeleton writebacks output buffers to ensure that CPU writes to the cache are flushed to external memory.

■The node's thread then replies with the status back to the GPP and then blocks waiting for the next message.

■Back on the GPP, the stub unmarshalls outArgs, the returned message is freed, and a status is returned to the application

3)When processing is complete, the application calls the VISA delete API (for example, AUDENC_delete() ), which causes the algorithm instance on the DSP to be deleted:

■The GPP-side forms and then sends a message to the remote node on the DSP with a command to "exit".

■On the DSP, the remote node wakes upon receipt of the "exit" message and sends an acknowledgement back to the GPP.

■On the GPP, a node "delete" message is formed and then sent to the dispatcher on the DSP.

■The dispatcher wakes up and deletes the remote node's execution thread.

■The node-specific "delete" function (for example, AUDENC_delete() ) is invoked to free algorithm resources and to do any node-specific cleanup. (Note that this call is from within the dispatcher execution context.)

■The remaining DSP-side instance object is deleted, and a response is sent back to the GPP.

■The remaining GPP-side instance objects are deleted, the remote node message queue is closed, and then a status is returned to the application.

2.1.3What About Single-Processor Systems?

On systems where there are no "remote" codecs, there is no need to configure a Codec Server.

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.
