MP_convert_cmi
This procedure may be used to make a loopback between equalizer output
and burst builder input. It converts the 114 soft outputs (CMIs) of the
equalizer located in cmi_buff_id into 114 ‘hard’ bits. These bits are stored in
buffer info_buff_id.
MP_exec_reset
22
cmi_buff_id
info_buff_id
This procedure is used to execute a reset synchronous to the input
message queue. The difference to the RESET message is, that this
procedure is not executed immediately after it is found in the input queue.
The reset_action is the same as the one of the RESET message.
MP_if_enough_audio_in_samples
60
reset_action
This procedure is used for conditional execution of procedures. The
following n_procs procedures are executed if the audio input FIFO contains
at least n_samples samples, otherwise the procedures are skipped.
MP_iom2_disable
42
n_samples
n_procs
This procedure disables the IOM
-2 interrupts of the DSP. This results in a
reduced computational load of the DSP and therefore also in reduced
power consumption.
MP_iom2_enable
44
This procedure enables the IOM
-2 interrupts of the DSP. Sending or
receiving data over the IOM
-2 interface is only possible if this procedure
has been called. After reset the IOM
-2 interrupts are disabled. After the
call of MP_iom2_enable the audio FIFOs are initialized as follows: The
audio input FIFO contains 1 sample (value = 0xFFFD) and the audio output
FIFO contains 148 samples (value = 0xFFFD). This procedure must
therefore be called before the MP_AUDIO_SYNC procedure.
MP_offset_compensation
45
This procedure performs offset measurement and compensation. The
following function is performed:
(i_offset, q_offset) = EM_offset_measurement (n_samples)
MP_read_bbd_in_FIFO_init (i_offset, q_offset).
MP_read_audio_in_fifo
63
n_words words from the audio data input FIFO are copied to the buffer
buff_id in the DSP data memory. This FIFO collects the audio samples from
the ADC converter located in the handset. The procedure waits until the
FIFO contains sufficient data. The time-out is expressed in steps of 100
μ
s.
If time-out occurs a TIMEOUT_AUDIO_IN_FIFO error message is
automatically sent to the SC.
