Advanced ADPCM SOUND DSP for Mobile QS6400
1. GeneralDescription
.
QS6400 is a high quality sound DSP for mobile phones that plays music through a built-in
ADPCM decoder with sound font rom.
QS6400 is equipped with HWASS's QPCM synthesizer,which is capable of generating up to 64
voices with different tones.
QS6400 can also play two channels of wavefiles of differing sampling rates.
Since data in the FIFO buffer is processed on demand, the length of the data(MIDI & WAVE) is not
limited, making QS6400 an excellent platform for applications such as incoming melody
distribution service.
The MIDI handler built in to QS6400 can play MIDI data without an extra buffer.
Included is a PWM module for audio out with a maximum output of 500mw at 8Ω load
registance(PVDD=4.0V).
For earphone use, QS6400 provides a single-ended stereophonic output terminal.
To operate QS6400 to full capability, "Standard MIDI File(SMF) Format 0" is recommended.

3. Block Diagram
3- 1 Outline of Blocks
Advanced ADPCM SOUND DSP for Mobile QS6400
3- 2 Description of Blocks
Explanations about each block of QS6400 and flows of the signal are as follows.
1) Register Block : QS6400 has registers of 32 x 8 for storing control data.
Built-in 8052 can communicate directly with the register blocks,
which are used to change control values and communicate commands.
23 x 8 registers are used for this purpose.
The extra registers are available to support additional features.
2) SMF FIFO buffer : This FIFO is used in receiving SMF file blocks (128bytes) from Host.
SMF FIFO Buffer has two banks of memory block and each buffer is
filled with data according to REG_IREQ_TYPE (When bit 2 is "1" ) from
built- in 8052. When receiving a data request (IRQB) for the next
procedure you should read the interrupt request type register
(REG_IREQ_TYPE) to check which data is required.
3) WAVE FIFO buffer : This FIFO is used in receiving wave data blocks (64 or 128 bytes)
from Host. WAVE FIFO Buffer has four banks of memory block, of 64
bytes each. The buffer size is determined by user specification (using
REG_WAVE_CHAN). Each bank is filled with wave data accoding to
REG_IREQ_TYPE( when bit 1 or bit 0 is "1") If you intend to play
high-sampling-rate(up to 22khz) wave files, we recommend that you
use only one wave channel, due to the high transmission rate of data.
In this case, WAVE FIFO Buffer size is preset to 128bytes.
4) Power control : This block is in charge of power management.
You can select whether to enter or wake-up from power down mode.
5) Clock generator : This block is a clock generator for the internal master clock.
QS6400 need the external clock input to operate normally.
6) CPU & ROM : This block describes 8052 micom and 12k bytes program ROM memory.
Built-in 8052 interprets SMF and Wave file.
7) PWM Speaker out : This block converts audio data into PWM format.
It supports stereophonic audio out.
You can also mute this output.
8) Earphone out : This block converts audio data into single-ended earphone signal.
You should connect poled-capacitor and bypass capacitor.

9) D/A interface : This block generates 16bit DAC interfacing out for high quality sound.
If you have an additonal DAC, you can also use this interfacing out.
When you use the DAC OUT mode, earphone is disabled.
10) Sound font : This is an embedded maskrom for GM 128 sound map and 47 percussion.
The sound font built in this device stores the sampling data according to
GM 128 sound map. Additionally QS6400 has sampling data to support
korean traditional music.

4- 3 Detail pin descriptions.
POWER SUPPLY PINS
- VDD ( 4,27 )
- These pins are connected to a normal power supply.
- VSS ( 3,28,31 )
- These pins are GNDs of power.
- PVDD( 34 ), EVDD( 40 ),PVSS (37)
- PVDD is VDD for PWM block. It's capable of driving a voltage of MAX 4.2V down to 3.3V.
- EVDD is VDD for EarPhone block. Its range covers 3.6V to 2.7V.
- PVSS is PWM block GND.
POWER RESET
- MRSTB ( 21 )
- Reset is accomplished by holding the MRSTB pin low for at least 60 oscillator periods
while the oscillator is running. To ensure proper power-on reset, the MRSTB pin must be
high long enough to allow the oscillator time to start up plus 40 oscillator periods.
- RESET should be free from glitch noise.
- At power-on, the voltage on VDD and MRSTB must come up at the same time for a proper
start-up.
- After RESET, all registers and internal RAM are initialized to "0x00“
AUDIO INTERFACE
- Support to playback ADPCM wavefile(2 Channels)
- Separate wave volume control(0~255).
