Could A8 host share DSP image processing loading

Joey Lin

Hi, there:

Currently we have Video-M3 received capture images, passing to DSP via shared buffer for processing.  Video-M3 deinterlace and display video again via shared buffer after DSP has done its jobs.  DSP and Video-M3 communicate thru MessageQ.  

Due to the fact that the DSP loading  in our application is so high that it has caused frame rate dropping.  To diverse the image processing loading, we wonder is there any way possible that we may take advantage of A8 to share DSP loading so that M3 could pass images to A8 as well as DSP and DSP may also received images from A8 for post-processing? Is there an example for reference?

Thanks in advance for your expertise,

My platform info: TMS320DM8148 (Vision-Mid) 

600-MHz ARM® Cortex™-A8 RISC MPU

500-MHz C674x™ VLIW DSP

200-MHz M3-ISS/M3-HDVPSS 

Thanks in advance,

Joey from Altek
