The floating-point 60 MHz, 32-bit DSP TMS320C31 provides input/output signal conditioning support. The DSP is supported by 512 Kbytes of zero wait state SRAM that provides temporary storage and workspace for DSP operations and a 4 Mbit flash memory. Up to 32 input analog channels are optionally filtered after software gain amplification; instrumentation amplifiers provide differential or single-ended input buffering. A/D operations can be triggered internally or externally through the front panel. A PCI bus connector provides the interface to the host computer. This module can use an external power source for reduced noise operation.

Available Software Drivers and Software Tools:

- - C library DLLs
  - Linux drivers
  - Windows XP drivers
  - VxWorks drivers
  - LabView

Applications:

16 digital TTL I/O. The Local DSP can be used to simply move data to and from the CPCI bus or provide control for factory automation, automatic test equipment, and control systems where control feedback is necessary (PID control, etc.). Custom application software can be downloaded to the DSP via the CompactPCI bus.
