Data Acquisition Board

The AVR-32 is a PCI bus-based DSP and data acquisition board that can be used in both desktop and embedded environments. Itęs based on the 60-MHz Texas Instruments TMS320C32 floating-point DSP (512 KB of SRAM) and includes a Xilinx Virtex FPGA.

The A/D and D/A converters that form the I/O portion are high-speed, 12-bit components. The AD9223 3-MHz A/D can be upgraded to a pin-compatible, higher speed device. The D/A may be clocked at up to 25 MHz. The digital data connector can be connected directly to an IDE hard drive for high-speed data acquisition applications.

The FPGA can incorporate a large number of logical functions and link the local bus with the analog and digital I/O elements. It is suitable for DSP application and may be programmed by the PC host or TMS320 DSP.

The Boot Loader mode is fully supported for embedded applications. In this mode, the software is initially loaded from flash memory. So, with the aid of the onboard voltage supervisor, the AVR-32 operates independently of a host. The board also has 512 KB of flash memory.

A V360 PCI-local bus bridge allows the host to access the devices on the local bus. The DSP, host, and FPGA share the local bus. The AD9850 direct digital synthesizer (DDS) synthesizes frequencies 0 to 20 MHz in steps of .015 Hz.

The AVR-32 software development kit features an assembler, debugger, device drivers for Windows 98/NT/00, and utilities for the flash memory, FPGA, and DDS. The DSP emulator port is available for use with hardware and software development tools.

The AVR-32 costs $995 in single quantities. The development kit costs $400.
