How can i use Memory throughout

Other Parts Discussed in Thread: TMS320C6748

Hello.

I use the chip that TMS320C6748 to develop my design,the simulator I used is XDS560V2 STM,the CCS version is 10.1.0.

Now,I want to use the tools of ccs that Memory Through Analysis to caculate my DDR throughout(nomally,can operate as that Tools>Hardware Trace Analyzer> Memory Through Analysis,reference to <Trace Analyzer user's guide>).But when I started debug, I can't find the my toolbar doesn't have Memory Through Analysis.

I want to know why i can't use the function,did i do some wrong setting,or it doesn't support the chip TMS320C6748,or is my software missing the corresponding script? or another reason.Could you tell me how to achieve the memory throughout. Thanks.

The left one is my toolbar,the another one is that I copy form the <Trace Analyzer user's guide>.

    Hello,

    Note that not all devices support the same debug/analysis functionality. When Trace Analyzer is launched, it will scan for supported operations for that device and only show options supported by the device. The Trace Analyzer User's Guide is likely showing a screenshots for keystone devices (C66x), which supports more trace operations than C674x.

    Thanks

    Thanks for your reply.it means that c6748 may not support the Memory Throughout Analysis,right?

    Yes, CCS will query the device for all supported trace functionality, then populate the menu items accordingly. The memory throughput features were advanced capabilities that required additional debug logic that did not exist on all devices. It was mainly a C66x feature as far as I recall.
