AM5728: OCMC performance

Sung-IL

Part Number: AM5728

Dear Team,

I found the memory architecture of AM5728 is much different with Keystone1/2, and thus I think the data based on Keystone can not be used.

MSMC of Keystone2 has same clock with DSP clock, but OCM of AM5728 has maximum 266Mhz. I calculated maximum throughput as below, and could you please check if below my calculation is correct?

Thanks and Best Regards,

SI.

Hi Sung-IL
Looks like this post was locked without a proper response/closure.
As per Jian , the calculations look good.
Additionally I would like to point you to the following application note
www.ti.com/.../sprac46.pdf
As the resource for AM57x family. This is for DRA7x family of devices, AM57x shares a lineage with them , so you can leverage most of the data published in this application note.
Feel free to open another post , if there are more follow up questions on any of this.

Regards
Mukul
