A SigmaStudio project for a product we've been developing for awhile uses several Linear Interpolator blocks for linearizing gain controls and such, placed with an older version of SigmaStudio. One of them is shown below:
Funny thing is, I cannot find this block in the current Beta version. Although the wiki says it's still around:
Now, the closes thing I can find is an Index LUT with selectable integer / fractional input and output, which I suppose has replaced the Linear Interpolator. However, it lacks the Linear Interpolator's graph, and I'm not sure if it works the same way:
And so I'm wondering:
- Is the Linear Interpolator still included and I'm just missing where it is?
- If not, can I still leave this block in my existing projects (they load OK in version 3.13.1, but I have not tried compiling)?
- Can the newly designed Index Lookup Table perform a similar function?
Other cores such as the -1761 and the -1452, still have the Linear Interpolator intact. What gives?
