SuperStrips (SS)
SuperStrip = hit or track at reduced resolution
AM works on 15-bit SuperStrips
Hit, track ? SuperStrip via LUT (different map in each layer)
- XTRP track (21 bits): max flexibility, use all info to find SS.
- SVX hits (21 bits including layer): drop 4 bits (3-0), then use 17 x 15 bit LUT. Layer number can be different in hit and SuperStrip (but no plan to use this feature).
- SVX SuperStrip width must be a a multiple of 16 times the HF precision (1/16th of the pitch) ?SuperStrip width must be a multiple of silicon pitch (which is in general different in each layer)
