ARM Multimedia Users Guide Texas Instruments Wiki. Content is no longer maintained and is being kept for reference only Return to the Sitara Linux Software Developers Guide. Overview. Content is no longer maintained and is being kept for reference only Multimedia codecs on ARM based platforms could be optimised for better performance using the tightly coupled Neon co processor. Neon architecture works with its own independent pipeline and register file. Neon technology is a 1. SIMD architecture extension for ARM Cortex A series processors. It is designed to provide acceleration for multimedia applications. Supported Platforms. AM3. 7x Beagleboard x. M AM3. 5x AM3. 35x EVMAM4. GP EVMAM5. 7xx GP EVMMultimedia on AM5. Processor. On AM5. ARM offloads H. 2. VC1, MPEG 4, MPEG 2 and MJPEG codecs processing to IVA HD hardware accelerator. Please refer to AM5. Multimedia Training guide to learn more on AM5. Also refer to AM5. Graphics Display Getting Started Guide to learn on AM5. Multimedia on Cortex A8. Cortex A8 Features and Benefits. Support ARM v. 7 with Advanced SIMD NEON Support hierarchical cache memory Up to 1 MB L2 cache Up to 1. Dual issue of instructions. Neon Features and Benefits. Independent HW block to support advanced SIMD instructions Comprehensive instruction set with support of 8, 1.

Processor SDK includes ARM based multimedia using opensource GPLv. FFmpegLibav codecs, the codec portfolio includes MPEG 4, H. VGAWQVGA4. 80p resolution and AAC codec for audio. Codec portforlio for Processor SDK on AM5. The script file to launch multimedia demo detects the display enabled and accordingly decodes VGA or 4. In AM3. 7x platform VGA clip is decoded when LCD is enabled and 4. DVI out is enabled. Scripts in Settings menu can be used to switch between these two displays. MPEG4 AAC Decode. MPEG 4 AAC Dec example application demonstrates use of MPEG 4 video and AAC audio codec as mentioned in the description page below. The multimedia pipeline is constructed using gst launch, GStreamer elements such as qtdemux is used for demuxing AV content. Parsers are elements with single source pad and can be used to cut streams into buffers, they do not modify the data otherwise. LCD of DVI.

OProfile is a common profiling tool used on Linux platforms, a kernel driver and a user daemon is used to collect samples of data. This tool can be used to profile a huge variety of system level statistics. Please refer OProfile for additional details. Listed below are the profiling results of Mpeg. AAC in VGA resolution at 3. MHz and 1. GHz via NFS server. Profiling results are obtained from the serial terminal. In order to profile the multimedia application kernel has to be compiled with oprofile enabled. Followed by this, opcontrol has to be enabled for the first time. Setopp powerclocks application can be used to scale the clock settings, the example below shows the settings for opp. GHz using the setopp. Set to operating point 2 CPU 3. MHz. . Processor   ARMv.
