Important Notes

referring to the current C64x+ codecs download page: [1]

• the current implementation of C64x+ H264 decoder v2.00.002 does not support DM648 or C6455 since the values for the QDMA internal addresses are hard coded, and the memory map for these devices is different than the memory map for the DM644x/DM646x/DM643x

Workaround: for C645x, the DM648 native version can be used, though, since the decoder does not use VICP resources, and the memory map is similar. This H264 decoder version 1.12 is provided in the DVSDK 1.11 for DM648

• the current implementation of C64x+ MPEG4 SP Decode – v2.00.011 does not support DM648 or C6455 since the values for the QDMA internal addresses are hard coded, and the memory map for these devices is different than the memory map for the DM644x/DM646x/DM643x

Workaround: for C645x, the DM648 native version can be used, though, since the decoder does not use VICP resources, and the memory map is similar. This Mpeg-4 decoder version 1.11 is provided in the DVSDK 1.11 for DM648

• the current implementation of C64x+ MPEG2 Decode – v2.00.010 does not support DM648 or C6455 since the values for the QDMA internal addresses are hard coded, and the memory map for these devices is different than the memory map for the DM644x/DM646x/DM643x

Workaround: Mpeg-2 is not offered for DM648 devices so it is not possible to use it

• Jpeg decode and audio decode should not have any issue since they do not use QDMA

• the download page will need to be changed accordingly

To help in porting each application using a specific codec on a different platform please refer to application note sprab73 It explains very clearly what the changes are across devices and what needs to be done

Important notes

referring to the C64x+ codecs download page: [2]

• the current implementation of C64x+ MPEG4 Encode– v2.02.00.02, C64x+ H.264 BP Encode – 02.02.01, C64x+ MPEG2 Decode – v2.00.010 do not support DM648 or C645x since the values for the QDMA internal addresses are hard coded, and the memory map for these devices is different than the memory map for the DM644x/DM646x/DM643x

Workaround: since the H264 and Mpeg-4 native encoders for DM648 use the VICP, they cannot be used on C645x, so it is not possible to use them

• Jpeg encode and audio encoders should not have any issue since they do not use QDMA

• the download page will need to be changed accordingly

C64x+ Based Resizing Kernels

• Resize Performance is simulated using horizontal and vertical kernels. The resizing kernels in the Image Lib can be used to generate resizing algorithms. The resizing algorithms are not available from TI in the Image library.
• Optimized Polyphase filter kernel is available for upto 64 filter taps
  • Sub partitioned as 4 tap – 16 phase, 8 tap – 8 phase, 12 tap - 5 phase and 16 tap - 4 phase polyphase filter
  • Number of tabs can increment in multiple of 4 upto 16 taps.
• Assumptions
  • Data is for YUY420 Image with 16 bit input and 16 bit coefficient.
  • Data is in the internal memory.
  • Sequence of Downsizing
    • First horizontal resizing and then vertical resizing.
    • This is to enable better performance in vertical filtering.
  • Sequence of Upsizing
    • First vertical resizing and then horizontal resizing.
    • This is to enable better performance in vertical filtering.
• DSP is running at 594 MHz.
• The performance numbers are in Microseconds.
