RAM Specification
The user must reserve a memory space for the largest window. According to the example shown in
Figure 6
, the total number of characters/spaces are:
For example, to change the size of Window 3 from 3 rows of 6 characters to 5 rows of 4 characters,
the resulting size is 20 characters. The number of rows increases and the number of characters per
row decreases. The required memory is at least 20 characters.
Note:
A space is considered as being a character.
The memory allocation is made by blocks of 32 characters.
The maximum size of a window is 16 rows of 32 characters, or 512 characters. This corresponds to
16 blocks of 32 characters.
1 block is reserved for the color-boxes (see
Chapter 4: Character Specifications on page 20
),
leaving 20 blocks of 32 characters for character codes (640 characters maximum).
The RAM allocation for each window is coded in bits ALWi[3:0]. Window 4 memory allocation uses
the remaining memory space.
The number of memory blocks allocated for window “i” is (ALWi +1), the range of allocation is 1 to
16 blocks of 32 characters. The total number of blocks is 20.
Note:
If the user changes only 1 window allocation, the RAM addresses of the following windows change.
Consequently we advise you to write the allocation when the windows are not displayed to avoid
false images.
