EXT Connector
DSP specific extensions:
two LVDS link ports for communications in multiprocessor clusters
or interface to FPGAs, 4 bits wide, 1GByte/sec transfer rate.
BUS1
The external bus interface provides a high-speed parallel bus to external
peripherals and daughter cards. The bus operates in asynchronous and
synchronous mode. Synchronous transfers provide up to 500 MBytes/sec
bandwidth and are especially useful to connect to FPGAs and Fifos.
- D16..D31 of the 32 bit wide data bus
- A0..A5 and A16..A19 of the 20 bit wide address bus
- bus control signals (read, write, clock, etc.)
- two pre-decoded chip selects
- external wait state requests
- 3 interrupt inputs (also usable as DMA trigger)
- 2 general purpose I/O signals (can be mapped to I/O, timer, etc.)
- supports asynchronous and synchronous transfers
- programmable bus clock, 75, 83.3, 100, or 125 MHz
BUS2
Extends the BUS1 signals to 32 bit bus width. The serial interface
provides a glueless connection to industry-standard A/D and D/A converters.
- two high-speed synchronous serial interfaces
(2Rx, 2Tx, up to 50MBits/sec, via User CPLD) - D0..D15 of the 32 bit wide data bus
- A6..A18 of the 20 bit wide address bus
- 2 general purpose I/O signals (can be mapped to I/O, timer, etc.)

- 4 MBits internal memory
- 10 channel DMA controller
- Timer
Emulator Interface
An in-circuit emulator interface for DSP debugging,
compatible with all Analog Devices and third party
in-circuit emulators.
SDRAM
SDRAM can be used for both data and program code. Besides direct CPU
access, DMA transfers are supported between peripherals and SDRAM, and
between DSP internal memory and SDRAM.
- 64 MBytes (16M x 32bit)
- 125 MHz operation = 500 MBytes/sec bandwidth
- supports FlyBy DMA transfers (external bus - SDRAM)
FLASH Memory
A nonvolatile memory to store application programs, user data, logfiles, and
board configuration. The DSP by default bootloads its application program from the
Flash Memory. Permanently stored in the Flash are the D.Module2.BIOS functions
and the Setup Utility, a resident program for field updates via USB or RS232.
- 8 MBytes, uniform sector architecture
- 10 years data retention, 100000 erase and write cycles guaranteed
- hardware write protection for basic configuration and bootloader
- D.Module2.BIOS programming support
Power Supply
- 3.3V single supply
- all other voltages generated on board
- high efficiency switch mode converters
- power supply supervisor and watchdog
UART and Asynchronous Serial Interfaces
Asynchronous serial communication interfaces are an industry standard
to communicate with process control equipment or a host computer, either
via point-to-point connections (RS232 or RS422), or via a network/bus
topology (RS485).
The D.Module2 Setup-Utility,
a field maintenance tool resident in the Flash
Memory, uses the RS232 or USB interface to communicate with any PC.
- Dual UART with RS232 and RS422/485 line interfaces
(optional 2*RS232 or 2*RS422/485) - RS232: up to 230.4 kBaud, RS422: up to 3 MBaud
- 64 word receive and transmit Fifos
- automatic software (Xon/Xoff) or hardware (RTS/CTS) flow control
with programmable thresholds - Interrupt and DMA support, programmable trigger levels
- D.Module2.BIOS programming support
High-Speed USB Peripheral Interface
USB is used as a fast data link to a host PC to exchange data in realtime,
modify signal processing parameters, upload application program updates, etc.
The D.Module2 Setup-Utility,
a field maintenance tool resident in the Flash
Memory, uses the RS232 or USB interface to communicate with any PC.
- supports USB1.1 (12 MBit/s) and USB2.0 (480 MBit/s)
- 14 endpoints
- 8 KBytes shared Fifo
- Interrupt and DMA support
- D.Module2.BIOS programming support
EMC
Signal integrity and EMC radiation have been carefully considered
during the D.Module2 series design:
- power supply filter
- local filters for high-speed units
- controlled-impedance PCB and shielding
- optimized connector pinout minimizes signal current loop area
Local bus
The local bus decouples the asynchronous on-board peripherals from
the high-speed synchronous DRAM and the external bus interface.
Connectors
The D.Module2 uses industry standard IEEE1386 high-density connectors.
The boards are self-stacking without needing a backplane. A typical standalone
module stack consists of a DSP module, one or more data acquisition modules, and
an optional networking module.
These boards interconnect the top and bottom connectors 1:1 to route signals
and busses through the module stack. FPGA daugther cards can break this
connection to insert the FPGA into the signal processing chain, typically
between data acquisition and DSP.
Please click the connector on the module's top side for specific information.
UserCPLD
An in-system programmable Xilinx Coolrunner-2 CPLD (complex programmable logic device). This CPLD accomodates various user-specific interfaces like I2C bus, SPI, synchronous serial ports to interface A/D and D/A converters, bit-programmable I/O ports, quadrature decoder, PWM outputs - whatever your specific system needs.
The UserCPLD is (re-)programmed via a USB or RS232 connection without special programming equipment. The D.Module2 support package contains a variety of ready-to-use implementations, a free development system is available to create your own designs.

D.Module2.BIOS
The BIOS provides 'C' compatible programming support for on-board peripherals.

The Setup Utility can be invoked manually at module reset/power-on or called at
any time from your application program.
- Program and data file upload to the Flash Memory
- File download from the Flash Memory (e.g. logfiles)
