     1 // A few notes about this implementation of a RAM search window:

     2 //

     3 // Speed of update was one of the highest priories.

     4 // This is because I wanted the RAM search window to be able to

     5 // update every single value in RAM every single frame, and

     6 // keep track of the exact number of frames across which each value has changed,

     7 // without causing the emulation to run noticeably slower than normal.

     8 //

     9 // The data representation was changed from one entry per valid address

    10 // to one entry per contiguous range of uneliminated addresses

    11 // which references uniform pools of per-address properties.

    12 // - This saves time when there are many items because

    13 //   it minimizes the amount of data that needs to be stored and processed per address.

    14 // - It also saves time when there are few items because

    15 //   it ensures that no time is wasted in iterating through

    16 //   addresses that have already been eliminated from the search.

    17 //

    18 // The worst-case scenario is when every other item has been

    19 // eliminated from the search, maximizing the number of regions.

    20 // This implementation manages to handle even that pathological case

    21 // acceptably well. In fact, it still updates faster than the previous implementation.

    22 // The time spent setting up or clearing such a large number of regions

    23 // is somewhat horrendous, but it seems reasonable to have poor worst-case speed

    24 // during these sporadic "setup" steps to achieve an all-around faster per-update speed.

    25 // (You can test this case by performing the search: Modulo 2 Is Specific Address 0)
