W529XX Application Note
- 28 -
(11) Speech equation:
The program can accept ADPCM ( *.WAM) files or PCM (*.SRC) files during
compiliation and it will first look for ADPCM files. Therefore, if PCM files are used for better sound quality the
"*.WAM" file should not exist in the same directory. See the above description. In the speech equation, using "*"
for the local repeat and using "+" for combinative voices occupy around 160
μ
S each.
(12) Call macro:
To call a macro within the program, the macro name and the transmitted parameters must be
in the same line and the number of the transmitted parameters must be equal. See the following example:
Macro chk_keyin label0, label1, label2
.
.
endm
.
tg1:
chk_keyin keyin00, keyin01, keyin02
.
.
The "chk_keyin" is the macro name, keyin00, keyin01 and keyin02 are the transmitted parameters.
During compilation, the statement below the "tg1" label will call a macro "chk_keyin keyin00, keyin01, keyin02"
which will be extended and placed in the macro contents. When extending the macro "chk_keyin", "label0" is
equal to "keyin00", "label1" is equal to "keyin01", and "label2" is equal to "keyin02". So the "chk_keyin keyin00,
keyin01, keyin02" will be compiled to:
mv acc, r6
jp keyin00 @r6=0
mv acc, r6
sub acc, 1
jp keyin01 @r6=0
mv acc, r6
sub acc, 2
jp keyin02 @r6=0
jp keyin_over
Macros do not reduce the program size.
(13) Blank:
A voice group name must be followed by one full blank line without any instructions or speech
equations.
(14) Silence:
In this regard, the W529XX is different from the other
PowerSpeech
ICs such as the W525XX,
W528X, W523X and W581XX. The silence length in the W529XX will be automatically left shifted by 4 bits. The
silence length of the [123] in the W529XX will be equal to [1230] in the other
PowerSpeech
ICs. So in the
above example, [500] is equal to [5000] in others ICs and its period is about 0.853 sec. (sample rate is 6kHz).
The maximum silence in the W529XX is [FFFF] and its period is about 43.69 sec. (sample rate is 6khz)
