nv_small and nv_full difference

Open ferin08 opened this issue 6 years ago • 2 comments

This link on scalability configuration shows the differences in parameters for the two

However, I would like to know what impact these parameters difference would mean from an application difference standpoint.

as to application, I guess you means the nvdla_runtime. so, when porting from nv_full to nv_small, you have to change the low-level driver APIs related to configuration REGs. and nv_small may lack of some computation unit which you shall not using in your application code.

According to this, are sub units like RUBIK engine and BDMA not present in nv_small config?

Also is nv_small just a scaled down version of nv_full or are there important units removed from an application point of view?
