GENERAL DESCRIPTION

The AKD7719-A is an evaluation kit for the AK7719; a digital signal processor (DSP) with 4 channels

digital data interface. It realizes an easy evaluation of the audio system by just connecting to the target

product via digital input and output pins. A USB connection is adopted for control interface, enabling to

develop DSP codes with a PC.

CONTROL SOFTWARE MANUAL

■ Setup of the Evaluation Board and Control Software

(1) Power the AKD7719-A-MAIN evaluation board on and connect it with a USB control box.

(2) Connect the USB control box to a PC with a USB cable.

The USB control box will be recognized as HID (Human Interface Device). When it can not be recognized

correctly (e.g., unknown device is connected), please push reset button [yellow] on the USB control box.

(3) Install AK7719.exe to the PC. Then ready to evaluate.

The start-up image of control software is as below.

Figure 3. Start-up Image of Control Software

When the connection of PC with the USB control box is removed, it is required to restart the control software.

■ Download the DSP Program and Registers Software

1. Register Setting and Code Downloading

1-1. Register Setting

(1) Select the SCRIPT tab to set register values.

(2) “script_7719_test.txt” runs under the condition below.

FSMode11: 48kHz / 16bit Linear / I2S

(2)

(2) load script file (Example)

File: script_7719_test.txt

After loading the script file,

the AK7719 becomes running state.

Confirm that DSP/Clock block are

powered-up.

1-2. Code Downloading

There are four code areas as shown below.

Code Area Alias Function

Control Register CONT AK7719 operation mode setup

Program RAM PRAM Storage RAM for program code

Coefficient RAM CRAM Storage RAM for parameter used by program code

Offset Register OFREG Pointer for delay RAM address

Table 5. AK7719 Code Area

(Note 1) All codes (CONT, PRAM, CRAM and OFREG) will be provided by AKM.

(1) Click the download tab and see if the file to be downloaded.

Figure 4. [Download] Dialogue of Control Software

(3) Uncheck the “CRC_Check” box, click the write button to download DSP programs into the AK7719.

If a write error is occurred, check if the clocks are provided to the AK7719.

(4) Confirm Run state of the DSPRSTN button

Now, the AK7719 is in running state. Input signal to the Port#1(SDIN1) is output from SDOUT2, 3 and 4.
