META Linux Connected Audio (LCA)

The META™ Linux® Connected Audio software platform is a complete software solution for META processors that delivers audio from almost any source, including internet radio, flash memory devices, digital home music collections and, when combined with an ENSIGMA™ UCC Platform, digital or analog radio.

Key to this flexibility is the use of the Linux operating system (META Linux), which provides the network connectivity and filing system support, together with an open source multimedia streaming framework, allowing end products to be developed rapidly in a well-known environment.

Running on a single Imagination META ATP or HTP processor, the platform combines realtime and Linux application environments, taking advantage of the multiple processor threads provided by these multi-threaded cores.

Audio codecs and post-processing effects (using the META Advanced Audio Framework), along with other timer critical drivers, run on hardware threads under a compact real-time operating system (META MeOS Embedded RTOS). The Linux application environment runs on a dedicated hardware thread, offering excellent separation of Linux from real-time aspects of the system.

Example applications demonstrate how to configure and control all the software components within the platform.
