As can be seen from the memory map, if we assume our player can fit in 4k
|
||||||
|
we have roughly from $2000 to $9600 for memory. That's $7600 (29.5k).
|
||||||
|
|
||||||
|
If we could have single buffered, we could have had 256*3*14 (10.5k) for
|
||||||
|
decompress and 19k for file size which would let us play most of the
|
||||||
|
reasonable sized songs on our play list (KRW(3) in table at end).
|
||||||
|
|
||||||
|
If we need to double buffer, then we need 256*2*14*2 (14k) for decompress
|
||||||
|
and 15.5k for file size which still works, at least if the move to KRW(2)
|
||||||
|
sized files doesn't bloat things too much.
|
||||||
|
|
||||||
|
|
||||||
|
Proposed plan
|
||||||
|
|
||||||
|
Decompress 3, but in the room of 4?
|
||||||
|
|
||||||
|
1234 in memory
|
||||||
|
ABCC decode as ABC, then copy C to 4
|
||||||
|
when playing C, play from 4, bring in next 3
|
||||||
|
DEFF
|
||||||
|
|
||||||
|
This lets us have 14k of buffer, allowing 15.5k of compressed file.
|
||||||
|
Do we have the spare cycles for this?

for the catalog entry (and an additional for every X blocks used)
|

|

The Disk II / DOS3.3 can in theory hold 140k, but first 3 tracks

are reserved for DOS (12k) and the Catalog track (4k) and the

Hello program (512 bytes) and our chiptune player (4k), totalling

24.5k of overhead, with 115.5k free (462 blocks)
