Memory Block Operations
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
@todo list,string memory block operations:
|
|
|
|
- list operations (whole list, individual element)
|
|
operations: set, get, copy (from another list with the same length), shift-N(left,right), rotate-N(left,right)
|
|
clear (set whole list to the given value, default 0)
|
|
|
|
- list operations ofcourse work identical on vars and on memory mapped vars of these types.
|
|
|
|
- strings: identical operations as on lists.
|
|
|
|
these should call (or emit inline) optimized pieces of assembly code, so they run as fast as possible
|
|
|
|
At least we have memcopy() already and some screen related routines in asm
|
|

Bitmap Definition (for Sprites and Characters)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
to define CHARACTERS (8x8 monochrome or 4x8 multicolor = 8 bytes)
|
|
--> PLACE in memory on correct address (???k aligned)
|
|
|
|
and SPRITES (24x21 monochrome or 12x21 multicolor = 63 bytes)
|
|
--> PLACE in memory on correct address (base+sprite pointer, 64-byte aligned)
|
|
--> actually not needed because a block at the correct address, and an array using 3x21 binary values, more or less does exactly this already::
|
|
|
|
~ spritedata $0a00 {
|
|
; this memory block contains the sprite data
|
|
; it must start on an address aligned to 64 bytes.
|
|
%option force_output ; make sure the data in this block appears in the resulting program
|
