====== CTA Work Started ======

//16 July 2001//

Not much happened during the weekend, mostly due to the weather being incredibly hot. Work started on the final [[:glossary:cta|CTA]] (CT Analyser). Made a prototype. The density graph will get some development time so we can actually see a few [[:glossary:track|tracks]]. If they "look" good, we can make the timing table compressor (see older WIP). This will mostly bring down the timing table from 50 Kb to around 1 Kb.

BTW: where the 87 Kb average track size comes from:

  ~12500 * 4 = 50000
  ~12500 * 3 = 37500
             = 87500

12500 is the theoretical optimum track size, the *4 is for one timing table entry, which are 4 bytes each. The *3 is a track read 3 times to avoid most of the redumping //[This was later changed to 5 times - Ed.]//. The compressed track including timing table is expected to be 25000 bytes at most.
