Hi,
I am working on Cortex-A8 processor, this has NEON coprocessor.
Its possible to execute the Multimedia (like Audio, Vidoe, Graphics.....) components in NEON.
Is it possible to execute ARM instructions (Normal Applications), while NEON co-processor is executing multimedia applications?
Thanks and Regards,
Mallikarjun

Yes, the NEON unit in Cortex-A8 is well suited for handling software codec work such as MP3 and MPEG.
ARM have released some free-of-charge OpenMAX libraries which implement the low level (DL layer) of the Khronos OpenMAX signal processing stack. The ARMv7 version includes functions implemented in NEON which can be used as building blocks for codecs.

Yes. NEON instructions are forwarded through the ARM pipelines to the NEON unit, but the exeuction of NEON instructions runs in parallel to the execution of ARM instructions in the main ARM pipelines.
