66AK2H12: I would like to know if the throughput of EDMA3(L2 -> L2) to depends on the data size.

HI.

I want to know about EDMA3 throughput.

I have two questions.

1. According to SPRABK5B(Throughput Performance guide for keystone2 devices) document, the throughput of EDMA3 (L2 -> L2) is roughly 6GB per sec.

    However, as measured by the actual data, the 3GB per sec throughput measurements were measured.

   The measurement method reads the TSCL, TSCH. 

    The environment was set up as per the document.(AB-sync, acnt=1024, bcnt=128)

    Is the result of the above measurement correct? 

    Or do I have to make additional settings to make it look like a document?

2. EDMA was tested by increasing the size of the data from 1 K to 128 K.

    The higher the data size, the faster the throughput has been.

    In 1 KByte, the throughput is 0.14 GB per sec.

    And In 256 KByte, the throughput is 5.23 GB per sec.

    I want to know whether this is correct.
