Arius announces the PC104C31, a new PC/104 based DSP board featuring the TMS320C31. Utilizing two AIO format daughter boards, the PC104C31 supports analog and digital I/O. The PC104C31 can be a slave board on the PC/104 bus or, by booting from the on board 2 MB flash memory, the PC104C31 can run standalone. The firmware is updated from the host processor or via the communication ports. The PC/104 interface emulates a very high speed 16C550 UART to allow the use of existing serial port drivers under any operating system which runs on a standard PC. Or the PC104C31 can become a bus master to replace your existing CPU and control devices on the PC/104 bus.

Applications

The PC104C31 has many applications in signal processing and embedded control. It allows the use of a small PC/104 system in place of a full sized rack mount PC. Operating alone or combined with a high performance PC/104 CPU the result is a data processing system of unmatched size and performance.

• Industrial Control - Multiple inputs and outputs with high speed control.
• Vibration Analysis - Octal analog inputs and outputs allows PC104C31 PC104 DSP boards to perform low or high frequency vibration analysis. .
• Voice Processing - Multiple channels of high or low bit rate vocoders on a single board: CELP, LD-CELP, ACELP, MELP, VSELP, ADPCM...
• Digital Receiver - quad FM demodulators with near 96 dB of dynamic range.
• Modem Demodulation - QPSK or FSK demodulators.
• Real Time Data Acquisition - Octal channel 96 KSPS on 16 bit analog inputs and outputs.
• Multi-channel Sonar Processing- Octal channel 16 bit analog I/O supports beamforming and direction finding.
• Data Encryption/Decryption - DES, Triple DES and others.
• Reconfigurable processing - On board FPGA allows special applications to be developed in hardware.

Features

The high density construction of the PC104C31 supports many I/O and processing features. Surface mounted components and dual sided mounting provides an unusually high density of capabilities.

AIO Daughter Modules

AIO modules are small (1.4" x 2.0") modules which are used on our PC104 DSP boards to provide multiple types of IO expansion. While still meeting the mechanical outline requirements for a single PC/104 board, the AIO modules may be used with our PC104 DSP boards in many combinations to provide you with the exact IO capabilities you need for your application.

• AIOaudio - Octal 16 bit ADC and DAC up to 96 KSPS with analog filtering


• AIO2wire - Telephony 2 wire interface with DAA and protection

Soon to be Announced

• AIOcontrol - Dual 16 bit ADC and DAC up to 200 KSPS with analog filtering
• AIOvideo - High speed ADC and DAC up to 10 MSPS with analog filtering
• AIOreceiver - Quad Channel Digital Down Converter Module (Digital Receiver)
• AIOtelcom - T1/E1 Interface Module
• AIOisdn - ISDN Interface Module
• AIOusb - USB 1.1/2.0 Interface Module
• AIOdigital - Multi channel isolated digital I/O
• AIOserial - Dual multiprotocol serial IO plus IDE parallel I/O

Let us know what types of IO you would like to see. We also provide custom design services for AIO modules.
