TMS320F28379D: Why is time execution of DSS from JAVA longer than JavaScript?

Part Number: TMS320F28379D


Tool/software:

Hi,

I use DSS for a program load into RAM and run it.
I observe significant difference in execution time:

Java          1:23
JavaScript 0:40.

I expected the oposite results. JavaScript also uses java JRE, but through Rhino interpreter.
Why running Java class that access DSS is longer?

Regards,

Piotr Romaniuk

    Hello Piotr,

    We were not aware of this discrepancy. We never really benchmarked DSS performance from a Java application. Checking with engineering, they also are a bit surprised but don't have an answer why.

    Hello Ki,

    Does the architecture of these two options look like this:

    1) DSS[JAVA-API]  <-> Rhino[JavaScript interpreter] <-> my dss script

    2) DSS[JAVA-API] <-> my dss class ?

    These two versions use java virtual machine, right? (for executing Rhino and my-class correspondingly)?

    Regards,

    Sorry for the delayed response. I was away on vacation and returned recently.

    yes this is my understanding as well.

    Thanks
