The board consists of private SDRAM and Flash memory attached to the TMS320C31 DSP at 32 MHz. An FPGA provides the timing and control. Peripherals include a serial port and connectors for IP mezzanine boards. Flash memory is available for downloading programs into non-volatile memory. A PCI bus connector provides the interface to the host computer. The mezzanine connector area can be used for RS232, RS422, and/or RS485 drivers or other custom serial I/O configurations.

Available Software Drivers and Software Tools:

C library DLLs
Linux drivers
Windows XP drivers
VxWorks drivers

The TMS320C31 DSP generation is supported by the TI eXpressDSP™ set of industry development tools, including a highly optimizing C/C++ Compiler, the Code Composer Studio™ Integrated Development Environment (IDE), JTAG-based emulation, real-time debugging, and the DSP/BIOS™ kernel.

Applications:

For applications requiring low-cost, high-density I/O or unique combinations, the CPCI-C31-ISC8 is the perfect solution. The Local DSP can be used to simply move data to and from the CPCI bus or provide multi-protocol support up to the application level, etc. Custom application software can be downloaded to the DSP via the CompactPCI bus.
