• Signal processing
The DSP enables many functions including AGC, Wind Filter, monitor volume, monitor switching control, and
SG Tone.
• Output processing by FPGA
The FPGA receives recording signals and SDI output signals from the DSP and outputs them.
• Output
Monitor output signals (headphone or speaker) are transferred from the DSP through the D/A converter to the SP
amplifier and the HP amplifier.
Headphone output signals are output from the RM-237 board and RM-238 board through the HN-386 board,
IF-1182 board, and HN-404 board.
Speaker output signals are output from the KSW-62 board through the HN-386 board, IF-1182 board, and HN-403
board.
The analog line output (AV out) signal from the DSP is sent to the DPR-343 board through the D/A converter. The
media recording signal (bidirectional bus) from the FPGA is sent to the DPR-343 board.
Meter output signals from the DSP and SDI output signals from the FPGA are sent to the DCP-61 board.
Control
• The FPGA is totally controlled by the ARM CPU (IC900) on the DCP-61 board through the SIO interface.
• The DSP is booted (SPI boot) by the FPGA and is controlled via the FPGA.
• Analog audio circuit control signals are output by the FPGA.
Clock
• The audio system clock is supplied from IC900 on the DCP-61 board to the FPGA and is distributed from the FPGA
to the A/D converter and the D/A converter.

System Control
DPR-343 Board
The 32-bit RISC CPU (ARM) with ARM core is built-in as the system controller (IC2101).
It has the peripheral interface functions of SDRAM, USB, SCI, and I
2
C. It operates on a 27 MHz clock (X2000).
FLASH ROM (IC2007), SDRAM (IC2006), and EEPROM (IC2201) are mounted as the peripheral ICs.
It performs the system control through serial communication with IC702 (DCP-61 board) of the camera block system,
IC900 (DCP-61 board) of the video signal system, and IC1000 of the media recording/playback system.
Main functions of the system controller and peripherals
Reading operation switch information
Reading the switch information and the LED control are performed by I
2
C bus communication with each sub-
microprocessor.
• Handle switch: IC202 on the KSW-62 board
• Inside panel switch: IC200 on the SWC-54 board
• Power supply switch: IC202 on the RE-298 board
Clock IC (RTC) control
The AU-342 board contains a clock IC (IC700).
The clock IC (IC700) backed up by a lithium coin battery monitors the battery voltage via IC200 on the SWC-54 board.
The clock IC (IC700) and the system controller set and read the current clock time through serial communication.
