How to measure the MIPS of a ASP on DA830 EVM running PA/F

Zhaosheng Pan,

Please have a look at the below wiki page at section "How to measure peak mips"

Hi Zhaosheng,

Thanks for your post.

There is an option to select "CPU Load Graph" from the DSP/BIOS menu of Code Composer Studio to observe the MIPS load on the CPU and to understand this, there is an example demo (Example 5-11, Section 5.8, page no. 167) available in the PA UserGuide (which can be found in the Path: \PA SDK 100713\pa\doc\pa-ug_da8xx_100713.pdf) that explains how to increase or decrease the MIPS load (CPU load).

Also, there is an MIPS Load ASP algorithm in the Audio stream processing chain for PA Y and the details regarding the operation of MIPS Load are given in Appendix J (page no. 297) on the same document in the PA User Guide which can be found at the same path mentioned above. Please refer the same to get the API details that permits to exercise control over its operation.

Also, there are PA FIL library API's which provides a library of functions for programmers to implement MIPS efficient floating point audio filters for TMS320DA8xx family of devices and this is available as pdf document in the PA SDK installation path which can be found at (Path: \PA SDK 100713\pa\doc\pa-asp-fil.pdf).

Please check the release notes in the PA SDK installation path (\PA SDK 100713\release.html) in which you will get all details about PA/F Documents.

Also, please refer the below wiki for the PA/F Programming Interface for ASP algorithms:

Thanks & regards,

If I use readSYSCpuLoad to get the CPU load data, does that mean the (CPU load percentage)*(DSP frequency (300MHz)) = the total MIPS of the code running on it?

Thanks,

Zhaosheng
