[...] Iâd like to do some array calculations (FFT, rectangular to polar, filtering etc). Iâd like the option to run at high rates (KHz) which would suggest using asyn. Is there any standard for this? I could easily put the calculations in the asyn layer but I canât see an obvious way to build a processing chain with only one link. Any suggestions? [...]My 2 cent: my "standard approach" to implement complex algorithms on IOCs is, to use many records connecting to the same device support.
Also is there a standard for inverse subarray? Iâd like to combine 100s of scalar PVs into one waveform. [...]I agree that an "inverse subarray" and a "waveout" record would be nice in EPICS base.
