DM814x Processor capability

Swapnil Kanani

Hi,

We have below requirement for one of our hardware

1 channel HD (1080p30) encode
3 channels SD (480i60 or 576i50 ) encode
1 channel of SD (480i60 or 576i50) decode
Target power consumption <= 14W

We would like to use DM8147 for above use case. Does DM8147 has sufficient horse power to support simultaneous encode of one 1HD input and 3 SD input and decode of 1 SD. In case DM8147 doesn't have sufficient CPU bandwidth, please suggest suitable solution.

Best Regards,

HI Swapnil,

DM8147 is capable of 2 1080p30 (encode or decode)

so,

it is possible to have

1 1080p30 encode

3 SD encodes

1 SD decodes

IVA Codec team, please correct me if I am not right.

Coming to power, the DM8147 device can very well meet the specs of 14W or less. Nonetheless, please use the Power spreadsheet and get an estimate on the power needs.

Hope this helps!

Best Regards

Hi Feroz,

DM8147 has only one HDVICP running at 450MHz while DM8165 has two HDVICP running at 450MHz. Do you see bottleneck in performance if we use DM8147 for above application as against usage of DM8165.

Hi Swapnil,

Yes, DM8147 should be satisfying the need for the above video capability.

DM8165 can do double this in terms of video coding.
