Modern CPUs to include SIMD instructions which are particularly suitable for processing multimedia, and this is a trend that is arriving to the embedded designs as well. Even when some platforms may provide dedicated dedicated hardware for audio and video processing, it may still be necessary to make a good use of the main system processor for other kinds of data processing. Not to mention that optimized software also uses less battery, which is a main concern for portable embedded devices.

We implemented a MIPS back-end for liborc, a library which provides an architecture-independent API to process data streams, generating machine code via JIT optimized for the task and processor at hand. The target platform was the modern MIPS 74kf cores, which include new SIMD instructions. With the MIPS Orc backend in providing performance improvements of 5 to 10% to various GStreamer components.
